Dap,
Major bummer is putting it lightly !!
My route takes just about 3 minutes to load and 45 seconds to "Auto Save".
What I do is create a "template" session that has all the "industry settings" in it. If I open the route WITH the template session, and if I get the error, I use the "Save As" (Saves ASS) command. The next box that opens should have the route name you opened to "save as". It works fine . . . the ony thing is, all other sessions other than the one you opened will be detached.
There is a way to re-attach sessions by putting it in edit mode and finding and assigning the correct map kuid will attach the session to the route again. I haven't tried it yet cause the sessions that got detached were all in-prgress, so I started over and its al under one session for now.
I haven't relly gotten into lots of sessions yet . . . but its gonna be a pain when I do.
Today . . . my AUTO SAVE hasn't worked yet. GRRRrrrrrrr . . .
I just ordered an import version of 2006 to see if that version has the bug. I am more and more thinking that we are in the realm of "Very Large and Complicated" routes that 2006 doesn't like.
We are the few unlucky ones Auran didn't count on.
WAAAAAAAAAAAAAAAAA :'(
