As i feared, there's an occasional keystroke lag or "sticky" key when playing games. And extended keystrokes always disengage after about 8 seconds. Both are unacceptable. That's when it was hooked up to the USB. What i can't figure out is why the keyboard worked when first plugged in to the USB with Intellipoint drivers NOT installed and BIOS features disengaged. The keyboard worked on boot-up to enter setup but after engaging USB support, nothing! I've since tried all combos of USB and drivers on and off and it still refuses to work.
The USB ports are clean (brand new in fact) and the USB on the reciever might as well be new as it's only just recently been removed from the adapter. The PS2 socket, on the other hand, could well be dirty. But that doesn't explain why the keyboard worked briefly while connected to the USB. :sigh: I've tried everything else. I might as well pull it to bits and give it a dose of alcohol. Though all i have is over-proof Bundy Rum. Will that work?
