Yep..been trying it under W2K Pro as well as XP Pro for a couple days now, with the same results no matter what I do: On-Off-On-Off.... Works for a little while then goes flooey on me. It's almost like it has a built-in timer in it to disable itself. ;) I thought maybe it could be a RAM thing at first, but I have a gig and a half of RAM, not to mention 256 MB of vid RAM, so I can't see that as being the problem. shrug But dammit, I like the way it looks when it's working! Nothing but a tease... ;)
