If a build so lacking that people on a forum can find bugs in truly is GM then I am utterly disgusted. Disgusted that the state of software releases, and specialy OS relases have degenerated so much that farting one out with a, hey we'll patch it later, mentality is in the realm of the acceptable.
It truly is pathetic, I bought Leopard at launch and it had its fair of serious issues even after the few first patches.
With Leopard 10.5.0 I had some issues, too, but with the current version of Snow Leopard 10A432 I have not even one bug! It's working very good for me, maybe for some other users it doesn't.
Try to repair your permissions with the disk utility.
And by the way: if Apple will really launch Snow Leopard on 28th August '09, they have to announce it today (21st August)... if they don't, we don't have to expect a launch until September.
