Hi Tom, I'm using Windows 7 with both ( Guide8 and Guide9) installed. Guide8 keeps the trail while Guide9 cancels it.

Bill,

FYI, I use the red Add Trail option all the time and print it out before
each evening's (asteroid) observing and the trails remain until I delete the
trails, but the yellow trail length also works for me from session to
session and I DON'T have to reset the trail length option each time I
restart Guide 9...I use Windows XP....perhaps the people having issues may
be using a different OS.

Tom
