Recently I have had difficulty opening a couple of folders on my system -- windows explorer just hangs, and I have to close it using task manager, which, of course, causes my whole desktop to vanish. Even when it comes back, explorer doesn't seem to work well, and often hangs again. The folders that seem to cause this hold either jpegs or video files, and quite a few of them, but this problem has arisen only recently, though I can't relate it to any spacific hardware or software changes. Other folders with media files will open, though. I'm running XP Pro, on a 1.7mhz P4 system with 512Meg of Ram. Any ideas?
