I have had this problem twice and I sent a msg to support about it today. The file browser window can delete your script and it's directory by accident - don't try this on your live files! Create a script - for deleting. Save it. Click the open icon - find the script in the browse window. If you are not quick about double clicking this can happen - try it with click drag. The browser displays files in columns, select the delete script - click/drag towards the next column - to left - click the mouse again. The file will disappear. It will still show in the textbox on the window. Check the directory under program files\mercury interactive\..\tests - it's gone too. You don't have to drag far - just nudge it over and release the mouse. Ugly. This is with QTP 6.5 on both Win 2K and XP Pro.
