I noticed a problem on my Win7 desktop about a week or two ago. When I delete files or shortcuts, the icon remains on the desktop until I do a manual refresh. The Recycle Bin icon changes to full (if it was empty), and the file itself is actually no longer available on the desktop, but the icon won't disappear until I hit F5 or click Refresh. Any ideas as to what may be causing this? I haven't done any updating of drivers since this started happening, so I don't think it's a graphics driver problem, but of course, I could be wrong. Any help would be greatly appreciated, and thanks in advance.
