In the last version, any time I hit 'debug' B4ppc would reset with the 6 choices again showing at the top of screen. I have written a large program. When using debug in 5.50 and my program stops because of some error, clicking on 'debug' and then 'stop' will do nothing and I must go out of B4ppc and restart the whole system.
You are right about this one.
Apparently the Stop menu item doesn't behave properly (it has the same behavior of a Pause button). However, the Stop icon on the toolbar works properly.
This will be of course fixed in the next update.
