Task List Lockout

I have Windows Vista SP2 32-bit with the Classic UI. The problem I'm having is that anytime I finish watching a full screen video such as one played in VLC player and then go to update the task list, I can click on the task but I can't click any of the sub-controls such as "Close,RTM,Complete,Postpone,Edit,Delete". My temporary workaround has been to slightly move the entire RTM gadget off the sidebar and drop it back. That re-enables the controls and normal function. I realize this is a bit of an unusual circumstance but I would greatly appreciate a fix to this annoying problem.I can provide more system information if you'd like. By the way, THANKS for this great gadget.

Can you reproduce this on other computers?
On my Vista SP2 32bit, VLC 1.0.1 (and with windows media player, media player classic, mplayer also, actually) everything works fine.

Well......no I don't have any other computers in the house that run Vista.

I can collect debug information if you tell me what information you want about my system?
