Hi Han

All this feedback is great. So I'm keen to get a new snapshot released as soon 
as possible so that you can try that and see if you have the same problems. 
I've just got the Qt Designer/ColorTool tutorial example working - so I like 
to get that checked into the CVS and then do a new release. Then convert the 
tutorial to ruby and put it up on the KDE Developer's corner ruby bindings 
site. But if you can send me an example to debug in the meantime, please do. 
I've attached Qt.cpp with yesterday's fix if you'd like to try that and see 
if it makes any difference.
