glen, er, bill? My ADB keyboard has fits every once in awhile. But it just refuses to let a key do anything. Usuall the 'a' key is a culprit, but I'v also lost F13 and a few others. Then it will decide to behave again. So far I haven't done anything more drastic than fiddle with the cable and hold the offending key down for awhile until it responds. Well, nothing that I can repeat here...
