Vu sur amigaworld.net :
yes, we were told that on some (3.7 ?) systems it freezes.
However we were not able to reproduce it until now (on three different MorphOS systems, one even being a 3.8. beta) nor do we have any crashlogs / ramdebuglogs
From what we know until now it looks like a driver issue with some gfx-cards, but that's just a guess. Might as well be an audio driver issue or whatever.
we now know that the MorphOS crash is apparently happening due to a (Radeon-)driver problem. The issue has been reported to the MorphOS devs.
