Volker was the first I saw to post this on his site. Check out this image to see if this could be why it was pulled...this is the craziest thing I've seen Notes ever do. I upgraded my Notes Client from 6.5.4 to 7.0 when it went Gold. Note that between steps 4 and 5 I tried opening a document in step 4 and the document invisibly opens in step 5. By that I mean that I couldn't see that it switched over to step 5 but that I switched tabs and noticed it.
Also, restarting Notes "fixes" it for a while but the problem returns after a bit.
