Didn't know APC was actually "providing" anything, is the driver on the CD now? Sure wasn't on the APC CD I had, I did have it at one time, but it didn't come with the UPS (at that time). >For some reason Belkin screms cheap junk to me.

Office Max did drop the UPS, the local store manager said the issue was margin, hadn't had enough returns on either brand to be meaningful. -- bill davidsen CTO TMR Associates, Inc Doing interesting things with small computers since 1979
