Follow Problem when using 2 Computers

I am stuck with a problem which I cannot work out so I need some help.
I am using ISBoxer 41.14.912.1 and Jamba 4.1.1
What does not work is that the toons on my remote computer do not follow the toons on my local computer.
I run with a 5-man group with 1 toon as master at any time and the 4 other toons on follow, across 2 computers.
My local (desktop) computer is where I startup the local team of 3 toons and where I play from.
My remote (notebook) computer has a remote team of 2 toons usually running on follow.
What does work is that the toons on my local computer do follow the toons on my remote computer all OK.
Also the toons within each computer follow the other toons on the same computer all OK.
The problem occurs on my local computer when I swap screens by pressing F9 or F10, or when I press ALT-F to force all other toons to follow my current toon in focus.
The toons on my remote computer seem to not respond to the FTL settings on the keys broadcast to the remote computer from the local computer.
This has been working ok for several years across 2 computers.
I could always swap to any toon on any computer to become the master/leader and press ALT-F and all the other toons would follow ok.
I put ISBoxer into debug mode (CTRL-ALT-SHIFT-G) and selected the debug trace window and selected some key options to trace.
Then when I F9/F10 swap screens on any computer I can see 162+160+F12 (LShift+LCtrl+F12) being broadcast to all the other screens debug windows ok.
When I press ALT-F on any one screen on any computer then I see the correct FTL mod-key combination being generated for the character on that screen to all the other screens debug windows ok.
For example, on one character when I press ALT-F then I would see 160+162+F11 (LShift+LCtrl+F11) being broadcast to all the other screens debug windows.
Each character generates its own FTL mod attributes plus F11 key correctly to all the other screens on both computers ok.
In my team configurations I have something like:
Team-Local
Slots
1 Toon1
2 Toon2
3 Toon3
Also Launch
Team-Remote
Team-Remote
Slots
1 Toon4
2 Toon5
Computer
RemoteComputerName
So it seems that Team-Local on the local computer can follow toons on the remote compuer beacuse it knows the FTL mod attributes to expect.
However Team-Remote does not seem to know what to do with the FTL mod attributes for toons on Team-Local, so Team-Remote toons do not follow any toons from Team-Local.
In the Quick Setup 38, FTLFollow macro I used the Preview tab to see what code it would generate for a specific team.
For Team-Local, it generates a /follow with all 5 toons names and FTL mod attribues.
For Team-Remote, it generates a /follow with only the 2 toons names and FTL mod attributes for that remote team only - so it does not handle the FTL combos broadcast from the Team-Local toons.
This problem appears in the generated LUA code for the FTLFollow macro for each character also.
If I press ALT-F on any screen on Team-Local then I get a red error message "You have no target. You have no target." displayed in the top middle of the other screens on Team-Remote's screen.
I tried changing the FTLFollow macro so that it did a /target {FTL} and a /follow so that it had an explicit target selected to follow.
However that did not work because the remote computer does not know how to interpret the FTL mod attributes for the toons on the local computer.
If I enter the F11 FTL mod combinations in directly through the keyboard on Team-Local computer then I can force any Team-Local toon to follow any other toon in both teams ok.
However if I enter the F11 FTL mod combos through the keyboard on Team-Remote computer then only the Team-Remote toons can be made to follow.
On the Team-Remote computer, entering the F11 FTL mod combos for the toons on the Team-Local computer gives the error message "You have no target. You have no target." and no follow occurs.
I checked all the key bindings on all 5 toons. I bound and unbound all the F11 FTL key combos to remove any possible FTL key binding being used by some other wow mod.
Jamba seems to be working OK.
If I open up the Jamba configuration and display the Core:Team tab on each toon then I can see that the jamba master changes immediately on all the other toons to be the toon which now has the focus ok.
All the other toons become jamba minions immediately on both computers ok also.
I use Jamba auto-follow after combat. I have some melee toons so I do not want to use jamba strobing to follow the master while in combat.
So my guess is that Team-Local knows the FTL mod combinations for all 5 toons because it is configured to launch Team-Remote, because it knows what toons are on the remote team.
However the Team-Remote configuration does not know what team it is being launched by. The "Also Launch" dependant team relationship is one-to-many, allowing for many dependant teams on many computers to be launched by one parent team. However I think that from the point of view of each dependant team, the back-relationship to the launching team should be one-to-one, not one-to-many, so that the dependant team can guarantee knowing what toons exist in the launching team and all the other dependant teams. For static code generation from the profile XML to the LUA code, the dependant team characters should include the launching team characters and all other dependant teams characters with their FTL codes in the generated macros for FTLFollow etc.
The behaviour of the ALT-F, F9 and F10 keys in ISBoxer does not work on my local computer to force my remote toons to follow any more.
So I have tried just about eveything to fix this but I have run out of ideas now.
Some help would be greatly appreciated, thx
