Final fix for bug #373 ------- Comment #13 From Christian Walther 2007-07-15 10:04:56 [reply] ------- Created an attachment (id=229) [details] patch to reinstate the SDL cursor after an NSApplicationActivatedEvent Oops, you're right. My testcursor.c has diverged so far from the original that I missed that. In fact, now that I think about it, that issue isn't even addressed by the cursor rectangle patch - it is only concerned with windowed mode (and fixes the problem there as a side effect). The problem in fullscreen is still the same as before. How about the attachment for a fix? (I can confirm that [NSCursor set] doesn't seem to have any effect when called from QZ_DoActivate().)
