Taking space in the add/remove list is not normal, I'd take a cruise in my Registry Editor and check for any programs that were uninstalled that still have keys in the registry. Even better, I'd go and download jv16 Powertools from www.zdnet.com
and cleanup your registry. Right off the back after you installed jv16, click on the installed programs lists and check if there are programs you removed but still in your list; then go to registry tools and run the registry cleaner. You may be surprised at how many unvalid keys your registry has. jv16 use to be free but is now shareware/trailware, but it's worth the try.
