Yep, same problem on Windows. It's almost always a mistake to give 3rd party developers unrestricted access to your filesystem, because they don't care and will shit their files all over it.

I wish more applications were distributed by the Mac App Store, because I believe App Store distributed apps are more strongly sandboxed and may not allow developers to abuse your system like this.

Mac apps outside the app store can still be sandboxed, but they have to be signed.
