Re: USNO on your hard disk

Hi folks,

I have just found out another small bug of the newest version of
GUIDE7 (Jan 23). I wondered why I could no longer the see the USON
stars. If you already have the USNO on the hard disk and upgrade to
the new version the guide.dat file gets a bit scrambled.
It adds the MPC_PATH variable just behind the A2_PATH variable and
GUIDE won't find any more the location of the USNO. A caariage return
is missing. Maybe this is already known.

Best regards from cloudy Belgium, Josch
