I'm using Flash 8 and have no problems at all with the program itself. However, it seems that any folders with Flash project files in them (namely .fla, .flv, .swf, , .as, .html) will lock up from time to time (i.e. can't delete or rename any files therein) and I won't be able to close the folder. I end up using the Windows Task Manager to kill the folder. I can still, however, open the files themselves and drag them around the folder. When this happens, no other open folders/apps are effected. Just the folder in question. Bizarre, isn't it?
