You're welcome. Glad I could help.
And there's no reason to "feel stupid". It's, apparently, a fairly common problem.
I solved that particular problem (for me) by moving the Quest Watch to the upper center of my screen, making the watch list "fixed size", and keeping it minimized unless I actually need to look at the quest list. I also locked the window in place so it can't be accidentally moved. A key binding can be set in the default Blizzard key binding interface to min/maximize the Quest Watch window. Just open the key binding interface, and scroll down to the Carbonite heading.
