launcher.py crashes when controlled by cursor

[GoogleCodeExporter]

What steps will reproduce the problem?
1. open examples/launcher.py
2. right-click on menu with mouse (touchpad in my case)
3. scroll to the desired app with left-click-drag (not really necessary)
4. click on app with left-click and no drag 
5. The app opens, but the first red circle remains where the right-click took 
place.
6. Left-click on the red circle to try to release it and wamo, down she goes.

Using pymt master branch.
