Cheat Engine

[Corruptor]

Sorry for the wierd title but i cant think of a way to sum it up as its a rather strange thing. if you have a better suggestion for a title i'll change it

What i have here is a program (namely the warcraft 3 level editor). The editor allows to you to write some stuff in a (eyes-hurting, i must confess) scripting syntax called "jass" (ahaha), and im currently using cheat engine to plug in my own program to do some precompiling stuff (mainly Defines to this point, but its a huge relife allready.)

Now i thought that there may be a way to address the most annoying thing about the program: you can not use tabs to structure your text.
Well, in theory you can, as you are writing your text into a windows edit controll which obviously supports tabs. The problem is that some genius semmingly thought it would be a great idea to make it possible to switch through all the controlls the window offers by using the tab key. I know this is default today, but cmn, this is a bloody text field...

Well, now, whenever i try to use tab to indet something, it switches out of the edit controll into some pointless other controll instead. And i have absolutely no idea how to fix this:
1: the IsDialogMessage function is called all the time so setting a breakpoint is just as good as pressing the pause button
2: i cant find the WindProc function, nor do i know where to search for it in a MFC application (as i never learned MFC, i only know the flat WinApi)

Any ideas on what to do?
