Sleep & screen saver
My MacBook Pro will not go to sleep after installing Snow Leopard.
It WILL go to sleep if I close the lid; however, if I have it sit open for 15 minutes, it won't go to sleep. It attempts to sleep, but instead the screen will just go black for less than a second. It's just like a flash of black, and then the screen goes back to normal. It simply won't sleep.
Anyone else see this happen?

Yes. This is almost exactly the same problem I am experiencing since upgrading to Snow Leopard on a Black MacBook. The only way to have it sleep is by either choosing that from the Apple menu or closing the lid; otherwise this computer will not sleep at a specified time, which was never an issue before Snow Leopard.
Related, the screen saver will not function. It will not come on automatically after a set specified time, and if done manually will remain but a few seconds before closing to reveal the screen as it was before.
In other words, I presently have a computer that has no screen saver and will not sleep automatically.
In looking at the posts on this thread, such an issue mentioned infrequently. Which I find inexplicable, although aside from occasional sluggishness and a few other glitches apparently I've thus far escaped many of the more serious problems mentioned. While some have suggested the possible remedy of a clean install, aside from being a
huge hassle, at least one poster mentioned it not helping with sleep.
Be that as it may, whatever the issue, as Snow Leopard offered few new gizmos, supposedly designed to address past deficits, all the more surprising it should cause so many problems. What I would suggest to Apple, or anyone feeling these things par for the course, is the release of an imperfect OS is the fine art of someone such as Microsoft. Apple should know better.
