My keyboard, a ps2 microsoftie thats about got the legends worn from the
keycaps, has not exhibited any such behaviour.

No hardware updates here recently, the most recent addition being a wap11
for my lappy. And I believe that was up and running for at least 2 months
before this started. Mobo is an older (now) biostar, gig of ram, XP-2800
Athlon, 333 fsb. Accessory 4 port usb1.1 hub in front panel for usb
expansion. 7 usb devices total. But only 5 are alive ATM, and one of
those doesn't properly ID itself, a pl2303 usb-seriel adaptor thats
plugged in but not in use. $40 and it doesn't honor flow control either
style or way.

Thanks Uwe.
