"...Once I started the Guide 8 program I did have to press ENTER
to redraw the screen."

Wups! I see the 'setup.htm' page says that this is an unresolved
issue. I've revised that text to read:

"...A couple of users are reporting that when Guide starts up, it
doesn't show a chart. Then you hit Enter, or zoom in or out, or do
anything else that would normally cause the chart to be redrawn, and
you're back on track. The currently-posted version of Guide has a fix
for this; you can click here for the current version."

...which then links to http://www.projectpluto.com/update8.htm .
Thanks for mentioning this.
