I just discovered that one of my apps, when built with the new beta crashes upon minimizing/maximizing from tray bar.
Isolated events in the attached .mfa
1) Run Application
2) Press Minimize icon (now you either go to step 3 or directly to step 4, appears to be random)
3) Click on Application in Tray bar
It was a while since I built this particular project before today though. Thus I am not certain if this may have been an issue from the last Release Build or not...
