Well - I don't think you are actually *missing* one, as I think it was not there in the first place :-) There usually is space for two of those rubber parts under the RETURN key, but there is only one mounted there - so if you place two of them under the RETURN key, you miss one elsewhere :-) btw: if you have disassembled the whole keyboard, it might be a good idea to clean the gold contacts and the inner part of the rubber parts (with the small, round piece of conductive rubber) with a cotton-wool-tip and some ethanol or isopropanol alcohol (use at least 95% pure alcohol, and no aceton or other sharper solvents) - you get a much better keyboard reaction, just as if it was new :-) cu Michael -- Michael Schwingen, Ahornstrasse 36, W-5100 Aachen, Germany voice: 0241-876165 Univ.: michaels@pool.informatik.rwth-aachen.de <--- use this for long mails!
