This scanner was hooked up to my Windows 98 system previously and I had no complaints. I recently had to move it to a Windows 2000 system however and things have changed.I had to download a new software version to support Windows 2000. The new software version 5.12 includes a check at startup for a "Go Button". This scanner does not even have a "Go Button". So basically you have to keep the scanner powered on day and night or be forced close an error message everytime you restart or turn on your computer. Very annoying. Unlike the previous software versions, there is no way to disable this startup function.Keep shopping.
