I'm not a Unix person, but one of my practices I support still uses their very old Medical Manager System to look at patient history. Long story short, someone else replaced harddrive. Anyway, they asked me to look at it. After SCO boots, comes up to log into GUI interface. I log in with root and root password, and the windows looking environment comes up. No mouse on system, Looks like I should be able to ALT_F to pop down file menu. However, nothing moves when I try to navigate around with keyboard. Can you navigate without a mouse? Thanks.
