This is a recent problem: If I insert a usb jump drive/thumb drive and open a word document, close the document and then try to safely remove the usb drive it works. I can safely remove it.
However, if I insert the usb jump drive and attach the Word document to an outlook email, and send the email, I cannot safely remove the drive--says it is still in use: Can't close generic drive because it is still in use.
I have done this very systematically on both xp and vista computers with two lexar jump drives (different models and sizes). Same problem on both. Sometimes if I find an open process (winword.exe) and close it from task manager I can then safely remove the drive. Otherwise, I have to shut down and restart.
If I just pull it out without safely removing it, the file I sent in Outlook is corrupted.
