Steps to reproduce:
1. click the save button on the top left.
2. try to close the editor with the windows X on the top right
After that the editor close the project but stills there. It works fine if I make a new project or open another one, but won't close unless I don't terminate the process.
This do not happens always, and I'm not 100% sure it's caused always in the same way, but it happens VERY often by following that steps.
Operating system & service pack:
I'm using windows 7 sp1 in 2 different computers (laptop and desktop) both with the same problem
