I'm noticing a strange behaviour which could probably be a bug.

MoI suddenly doesn't respond until I hit the esc key and then I'm stuck in "rotation mode". I'm not able to select anything all mouse actions rotate the model instead. In this mode the keyboard shortcuts also do not work. Other than this MoI works as expected. The only solution to get out of this was to quit and restart MoI.

I'm sorry that I'm not able to be more specific but I noticed this at least two times in the last days. I cant say what causes it. Did anyone also notice this?
