It might help if you told us what "the debug window" was saying. Maybe it is a reason to update to 2.8, maybe it's something that's broken in 2.8 as well or maybe it's your code that's causing you grief.

Does this by any chance involve your attempts to alter the definition of Semaphore or to subclass it?

In a workspace in your 2.7 image, evaluate:

	EToySystem eToyVersion: 'Squeak2.8alpha' date:  Date today.

then from the world menu select help/update code from server. As Doug has just pointed out, this can be a very slow going from 2.7 all the way into 2.8. You can take his suggestion and download a clean 2.8 or you can apply my changes (recently posted) to smooth the process.

Well, "should" is one of those easy-to-say-but-sometimes-hard-to-do things. I suggested a solution to your previous Semaphore dilemma. Is this the same problem or a new one?

Cheers,
