ProcessExplorer (http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx) is a good way to see what process has a file open on Windows. This error is very unusual, since both JOGL and JOCL use the same way of unpacking files in a temporary directory, and we've tested it on many different types of systems without a problem. Maybe the user is somehow trying to run two copies of JOCL at once, and they're interfering with each other?
