g'day,
although this post is already old - we seem to now experience the same problem very frequently on a similar setup:
mc os 10.6.4 or 10.6.5 (some with the latest apple JAVA update others without)
archicad 13 / AUS3826
bim server
some of our users loose the following keys...
mainly shift and/or command
for others the screen does not refresh on either panning or zooming in or out.
any thoughts appreciated.
