My 2c -
Wait for Patch 2.
It's currently in RTS phase and will be released to web soon (within a couple weeks, best guess). And it resolves/avoids some reported problems that were specific to Patch 1.
But, if feeling pressured to apply "a" patch, you could review the Patch 1 known issues KB article. We try to keep that updated for folks contemplating patching.
Thanks for the reply. I had been leaning this way.
