Hi Bob and Bob,

Under Windows, you must run the DOS emulator in full-screen mode to get
the DOS clock ticks at the correct rate. If you minimize the
Window, the ticks will stop completely.

WindowsXP has a built-in clcck synchronizer but it will not
be frequent enough in auto mode to keep the clcok within seconds.

You really have to do an update every day if you want to
be on-time for orbit calculations either using the built-in
synchronizer or one of the add-on packages.
