I've been having a weird problem on Win7x64Ultimate: It started out as being unable to delete folders on my Desktop which contained any files. I am the administrator. The permissions are correct; verified against another install. In order to delete the folder, I have to delete all of the files in the folder. If there are subfolders, I have to start from the bottom deleting the files, then folders. Then it starting spreading to other drives. I know that the common advice, is 'oh, well, you have to empty the folder first...' NO. That is not the default behavior. It's a pain in the @$$ besides. I move A LOT of folders and files around every day. I want to fix the problem. I have scanned and scanned again, no virus/infection. The issue is so random. I've thought that maybe a program I use frequently is not releasing a Handle or something, locking a file, is that a possibility? How do I fix it? What is broken? Is it a setting? Does anybody have any idea what program/etc to use to monitor for open handles etc, so I can try to spot the problem? I'm seriously considering a re-install, with the days worth of backup copying and program installation. Any ideas? Thanks for taking the time, this is really frustrating!
