Left mouse click not working for all characters

I have multiboxed 4 throw barbs from character creation to paragon level 11 and I just realized when I shift left click two of the characters stand in place and attack while the other two just walk away. Right click works perfectly for all characters as do all of the numbered keys. It is just the shift left click that will only work for two of them. Does anyone have any idea as to what I am doing wrong? I had been using a fury generator on left click and just switched skills to something more useful which is why I did not notice until now.

Thanks

Right click works perfectly for all characters

I just want to say, this is exactly opposite of what the title says

Okay so for Shift+Mouse1, typically when it works in some windows but not others, and you're going to hate me for saying this too... typically it's because the setting in the game where you set Shift to stand still, is changed to another key.

When it doesn't work for ALL windows, then you would have to check the "Make game believe it is foreground window" option in your Character Set, but if it works for some then it's not this one. Probably the in-game setting.

Thanks for pointing out the error in the title. Problem solved! Two of the characters had a different key binding for stand still. I really thought it was to do with the setup of isboxer. Never thought to check in game settings.

Thanks again.
