ARGHG if its not one problem its another.

I have a IBM thinkpad t20 laptop with a ps2 splitter connected to the ps2 port. I then have a 5m ps2 extension going from the ps2 splitter to an illuminated external keyboard.

Heres the wierd thing.. its been working great for months but all of a sudden it just stops working after pressing a few keys. For example i press the Caps lock key 5 or so times then the whole keyboard just stops responding! Can't be a loose connection as if I log off XP Pro then log back in the keyboard works fine again!!

Was thinking its somert to do with the software but I cant think what. Device Manager shows up fine with the keyboards.

Any suggestions?
