Seems that the tool tips -- those little informational pop-ups that appear when you hover over an icon -- aren't working in my preview window. This is the case with all, except one: the small "x" close icon that appears when the preview window is docked.
They work correctly in all the other modules I've checked.
Anyone else noticed this?
EDIT: It occurred to me that I've seen this before, in Vegas 5, but on that occasion, NONE of the tool tips worked. At any rate, everything was working correctly when I started it up this morning. Restarting Vegas 6 a couple of times last night didn't take care of it, though.
Thanks to those who've replied.
