SCO Execs are dumping shares. Let's see if the universally hated Linux rival's only friend - Microsoft - steps in with another Band-Aid.

Linux, developed by Finnish programmer Linus Torvalds in 1991, is being expanded by thousands of volunteer developers.

Red Hat Inc., which makes Linux business software, also has filed suit against SCO.
