VistaScan update for Win2000. The only function not supported are the front buttons on the scanner. Twain drivers work great. Drivers released Oct. 19, 2000

This scanner is completely unstable under WINDOWS XP. Sometimes it works (vary rarely) but the most times doesn't.I tried updating the drivers for XP, I run the patch for XP drivers update...but the scanning result is always a BLACK PAGE.

Exactly the same like anonymous wrote. 5% working - 95% black page. So I think i'll garbage it (because when I need to scan something I have to pray to God for success!) It's like lotto.
