The past month or so every time I try to click a dropdown arrow it doesn't allow me to pick from the expanded menu
It happens also when I open the the personalize window to change my screen saver. I can't scroll down to see the link to click to access the screensavers the sidebar will keep going up the more I pull it down.

I have scanned and re scanned my system no issues. These things are not happening every time. but they are happening enough to be a pain in the butt.
