Thanks cdrsubron7, that does work good.

I was trying to look at their contents as they are "running" in the player though. If I "Pause" the play, I can look at the properties page for the group, or for a waypoint, but not the contents while it's playing. If I "Stop" the player, I can look at the groups "scheduled" contents, but not what was actually "in play" at the time of trouble. Oh well. We'll have to do LOTS of "testing". Darn the luck, but someone's gotta do it.
I did discover one thing though, and the RGGs that were "stuck" - there was actually four of them, once I zoomed in closer on them, two in one "harbor" from the same RGG. What I found were six waypoints in the three RGG definitions (two each) that were set to a speed of 0.000001 knots. That would explain an apparent lack of movement. I've set them all to a "1" (one) knot setting for a minimum, and when I just ran it again, all ships were back at "home port" by April 15th, 1942, just in time for taxes... Thank God for the 010 editor's Find / Replace... Now, if I was just a little better at the Find... has anyone seen my reading glasses?...
