You did not even start class yet, TPT is not realistic.
I'm 2-3 weeks late, but tested the beta just now and it works.
Thanks!
-- Edit --
It works the first time you run it; the second time you run it, the issues are back ( prefs are not loaded, stamps are not loaded, etc. )
I have no idea why.
Was this issue ever solved? Because I just tried to download the most recent version for Mac, and I am still getting the "You don't need to install the powder toy on Mac OSX" message. I still can't access my saved stamps or saved simulations, and it always logs me out. Even though I downloaded the most recent version, 89.2, it still shows up as being 89.0...
I really like the powder toy, and this issue has made me use it less and less and less :(
Here is a photo of the window on startup.
