Hi, Michael told me that he got an error message when he tries to eject a HiMD using "eject" menu item in windows explorer while QHiMDTransfer is running. This is not a bug in our detection code. The error message may occure when you are logged in without admin rights. To avoid this you can change windows security settings. Read http://support.microsoft.com/kb/256592/EN-US/ how to do that. The article applies to Windows 2000 but it will work on Windows XP (tested with SP3) as well. Thomas
