dxNothing Window Not Loading in Layout
I have been using ISBoxer with two WoW characters in a simple layout - one on my primary monitor, and one in the bottom third of my second (vertical) monitor. Getting ready for WoW classic, I'm trying to get a dxNothing layout set up so I can run mouseover heals while playing my mage. I attempted to follow Mirai's instructions in this video - https://www.youtube.com/watch?v=Hntr1IE1Xgc - along with the wiki regarding the dxNothing character. The only discrepancy I've been able to catch between my settings and Mirai's, is that the VFX Create key map requires me to enter the window size as ####x#### instead of ####,#### (it resets the values to 0 if I use a comma).
Currently, my two WoW clients load correctly - stacked on my main monitor. However, the dxNothing window will not load into region 3; not even as a black box.
I've tried every combination of VFX check boxes throughout the dxNothing character, layout regions, layout wizard, key maps, etc.
Thanks in advance!
