Fixed bug #899 Jeremiah Morris 2009-12-09 16:23:50 PST Re-enable mouseLocation workaround on 10.4, 10.5 OS X systems before 10.6 have a bug with [NSEvent mouseLocation] if the screen resolution changes. SDL_QuartzVideo.m contains a workaround for this bug, but it was placed inside an #ifdef in revision 4762. The comment reads, "I'm gambling they fixed this by 10.4." After seeing this bug on several Tiger and Leopard systems (both PPC and Intel), I can confirm that it's not fixed until 10.6. The workaround doesn't compile for x86_64/10.6, so I can understand why it was segregated, but it needs to remain in place for the i386 and ppc versions. The workaround causes no problems under 10.6, even though it's not necessary there. Patch is attached with one method of keeping the workaround active on the systems that need it.
