I've been having intermittent issues with the Vista UI as of late (Home Premium SP2 clean install) where the taskbar minimized items will become unresponsive (clicking animation but the program will not maximize) and items such as checkboxes will have a similar issue where the clicking animation shows, but no action is taken(no uncheck/check). This does not seem to affect checkboxes inside some programs such as firefox, excel, etc. Currently I have the Windows update screen open and it is happening right now.

So far I've run Windows repair thinking explorer may have become corrupted. According to windows nothing was found. I've checked the reg for bad entries, and have removed any shell enhancement programs. (Not that there were many to begin with but just in case. Maybe some left over reg entries from said programs?)

Interestingly this seems to affect some games that use keyboard shorcuts and keypress+mouseclick shortcuts in a very similar fashion where the shorcut notification will flash but no action is taken.

Have you checked Event Viewer for possible clues?

It was one of the first things I had done. I hadn't seen anything that correlated until today. Sifting through the folders I noticed that the diagperf.dll is throwing events at or around the same time when problems start. I don't know if thats really it but I'll keep looking.

From Event--

Diagnostic module {282396b2-6c46-4d66-b413-70b0445df33c} (%SystemRoot%\system32\diagperf.dll) finished troubleshooting scenario {186f47ef-626c-4670-800a-4a30756babad}, instance {429dca75-0a35-4886-aefa-678f0f38edb6}, original activity ID {00000000-0000-0000-0000-000000000000}. No resolution was set by the diagnostic module.
