When I click on Project Settings in the editor view it takes more than 30 seconds to load. Initially the top of the application window indicates "(Not responding)" and then 30 seconds or so later the Project settings window appears and all is back to normal. Any suggestions on how to solve this? Maybe I should try renaming some folder that contains settings so Studio can reset itself?

I should add that I already tried restarting the application and the computer. It makes no difference. It's a problem that's been with me for a few days now.
