A more interesting ( possibly ) question is : why does the K/B hardware react like this : If <shift> is down, and then <arrow up> is pressed, The interrupt handler receives : <extended shift> off, <arrow up> down ? This really cocks up handlers that use the same map for extended and normal keys. ( By extended I mean a dual code thing 0xA0, code ( perhaps ) ). Is there any logical reason for this / is this a figment of my imagination ? Regards, Michael Meeks. -- mejm2 AT hermes DOT cam DOT ac DOT uk <><, Pseudo Engineer, itinerant idiot ...
