OK thanks, but I'd be grateful for answers to my questions 1 & 2 if you could please.
For question #1: There will very probably not be a new release prior to the final release as we are now scratching at the door of Adobe MAX; that's when Adobe does their formal releases. So, in the next day or two, keep your eye out for updates; those should be good.
#2: When these new releases arrive, please do the Bridge update THAN the PS update. Hopefully, you should not need to uninstall and reinstall. IF YOU DO need to do a reinstall, I'd just carry along any prefs as they are the issue: instillation order is the issue. There should not be a need to start with fresh prefs.
Please let us know what happens.
