Sorry to hear that. Trying to make windows partially transparent will do
that to you. :-/

I don't know very much about Superkaramba but I believe it doesn't actually
paint onto normal windows. If you are using a platform that supports
window composition then it may be possible to do this with "normal" PyQt
applications, but otherwise you may well be disappointed.

There is some information about this in the qt-interest mailing list
archives:

Basically, unless I'm missing some information, it's not as simple as one
might expect. You might get more suggestions for ways to do what you want
by looking at the qt-interest or kde-devel mailing list archives, or even
asking on there:
