ENGLABENNY  Good to hear it works well. Thanks for your input.

Right now the chance for fixes is very small; I'm not working with OS X very much at all at the moment (just linux for me).

1. I can provide the source code for QCDesktop, it is open source, but I haven't documented or cleaned it up yet.

2. It's very hackable, very easy to edit this application or just remake it. So programming types could do it again pretty easy.

3. The fix for that specific problem is probably pretty easy, found an apple doc example that seems related. I never used any compositions with mouse inputs, I think that's why I never tried that. Any links?
