I never thought about qt3 compatibility but It seems to me that renaming the 
qt3 compat classes and revert the header file name changes should suffice to 
compile against qt3 again. But then somebody else has to do the makefile magic 
to support both versions. Also which version should be prefered if both are 
available?

I can click in the window around and closing the window using the X button 
asks me about saving the changes. Which QT version do you use actually?

Best regards
