On the Fred Miranda forum PP a guy said he talked to Adobe and that a fix was gonna have to be made on LR2 and Adobe will be releasing one soon.
Uh huh. . .and I got a bridge in the desert I'll sell ya...
Look, there are a "few" know issues with the GM release of LR 2. I'm not at liberty to sya what and when any sort of fix will be coming but I will say that the VAST majority of people's issues seem to come from sloppy machines with other problems besides Lightroom, corrupted registries or preferences, bad catalog upgrades and lack of optimizations or a whole list of potential local machine issues.
If you want to contribute to the discussion, it would be useful to supply the basic troubleshooting info and what you've already done by yourself to troubleshoot;
Basic things such as uninstall, reinstall
Trashing the preferences
Testing a new catalog vs an updated catalog
Whether or not you've optimized the catalog
Where the catalog is relative to the image storage.
What admin privileges your user account has
Trying Lightroom in a new user account
The size of your captures and whether you are using native raw, DNG or TIFF/JPEG/PSD
Unless you give the basics of the information required to reliably review your situation, all you are doing is adding chaos and white noise to the situation...which will do nobody any good at all.
