I tried Tonight for Windows too on my win2000 box.
seems to run aok, no tweaking. the printed output
appears ok but I hate printing paper and the screen
output lacks in sense that it does not "clarify" the
setting of moon, ie, I always want to know when the moonsets
after the last sunset, but on night(s) when the moon does
not set that date, the screen is showing you current sunset
for that day but the previous moonset from last night (am)
YES, I too use Guide, &&
or usno mica does fine too, I create text file for month, and
just open it and see what's what.
another high accuracy moon app is mooncalc 6.0 DOS.
