I've reproduced this bug now on my machine.

With the aid of the WATCOM debugger, I've determined that the
exw.exe heap (malloc/free area) is already corrupt inside the
routine getText() before this call to c_func() is made:

     iLength = c_func( xGetWindowTextLength, { hWnd } ) + 1

I clicked the ADD button after typing a 12-character
string. (I'm not sure if the length of the string is really that important).
I haven't found the place where this corruption actually takes
place. That may take a while. Maybe someone has an idea. It still
could be either a exw bug or a win32lib bug, I can't tell.
