Having problems deleting/moving/copying .avi files in windows xp?

Just so all you WINDOWS XP users know.. Virtual Dub 1.4.7 has problems frameserving in Winxp... check out digital digest's forum as well for numerous other accounts. Basically, you can fameserve with virtual dub, however, you will find that any .avi files will start misbehaving.. ie.. you can't delete them or move them or copy them as a message will say cannot (move/delete/copy) file as it is being used by another person or process.. it doesn't matter if you restart or not. I couldn't figure out why this was happening so I figured it must be something to do with converting movies.. so I went into the auxsetup of virtualdub and tried to uninstall the handlers.. it said I couldn't because one of the *.dll's was in use.. even after a restart.. the only way I could fix it was to go into safe mode, run auxsetup.exe, and uninstall the handlers.. then my avi files worked properly. Just a heads up for you all as I was VERY frustrated.
