Thank you, Damien. This has been the most constructive input. However, I woke up this morning, simply removed the voodoo hack and the thing works!! I don't understand it at all. I haven't changed one bit of the GTK+ code. I just woke up, read the emails from you guys. Started to mess around with the voodoo stack hack, removed it and the thing works just as all the other widgets. I haven't got a clue why it is so. I'm using MinGW on Windows and I often hibernate the computer, maybe it was just a bug in the hibernation recovery and it somehow influenced the stack issues. I don't know. It's totally weird. Or maybe it was some local linking compiler error, since the app is using more files. I don't get it, cause I didn't even compile all the files, just used the makefile to recompile the particular file that takes care of the GTK+ layout. Well, anywayz, thanks for your thoughts. The voodoo is gone just as it came, maybe the warlock died : ).
