I updated to Java 7u15 and that didn't fix the problem, but after uninstalling every other version currently installed and reinstalling 7u15, it worked. I believe the problem was linked to a older 64-bit version taking precedence, but now the problem is fixed. Thanks for the help.

I just purchased Spine (v1.0.16), and I've started messing around with it, but when I go to Save Project or Save Project As, the window dims briefly and then goes back to normal, with no other changes. The same happens when attempting to use any Browse dialog. I've tried running the program as Admin, and in XP compatibility mode, but nothing's working.

I'm running Win7 Home Premium 64 bit.
