CADIAN 2010 HAs started to develop some unusual actions. 1. use a command ( example copy) and press enter - cadian gets the help menu - not the last command used. 2. drawing display area has lost some space. approximately 15% of screen along the foot of the drawing is blank - no display - pan on drawing and contents disappear. 3. Cadian occassionaly displays UNKNOWN ERROR and aborts the current command. I am unable to attach a file to this email - will send seperately please advise. regards Ewan Hall ewan.hall@unoms.com.au
