Git commit: e523aad / Windows7

1) "My First Score"

2) Press "P"

3) Try to enter some notes

Result: nothing happens

4) Continue by clicking on the piano keyboard. After some more clicks (more or less a dozen), the program hangs then crashes.

doesn't crash here, under debug, but goes into a loop, saturating one the the cores of my PC, memory usage growing at a pretty highg rate up to 3.6GB (the max. fur a 32bit program under Windows I believe), then exits normally.

I'm not sure, but I think that the event is not really removed from the QQueue at line 1740 of cmd.cpp.
Probably because the handling of midiInputQueue changed in the big commit (now it is called through a function).
