I've tried every suggestion in this and other similar threads, but other than resorting to full screen mode, I always encounter this debilitating bug. As this has existed since the first betas of 2.0 and has yet to be fixed, I have to say I'm very disappointed. At this point, being the "long time Mac user" amongst several people who have switched, are switching, or are planning to switch to Macs, I've had to point them all to Parallels.
