If I try to start UFT from the .exe file or from a shortcut the screen goes black with a complete line of short vertical lines across the top of the screen. This locks the computer requiring a power off reset. This same computer had been running the UFT 3.0 program without previous problems. I am using Windows 98 and have plenty of available memory and disk space. I have tried uninstalling and then reinstalling with the same result. My data is protected in a backup but without the UFT program 7500 names and research data is in limbo. Can anyone help???
