I first noticed this problem when trying to empty the Recycle Bin and then realized that it was happening with all my desktop icons. When I right-click, the cursor hangs up on the hourglass; the only remedy is to kill the process in the task manager and restore the active desktop.
Programs seem to run fine- even right-clicking within an application is OK, this seems to be an Explorer issue.
Seems more irritating than critical, but thanks in advance to anyone that can offer any advice.
