OK, I built an activity using the MP3 route. I run the time and watch the trains. Everything looks fine.I do a Compute and Save. Now I run it again just to be sure and trains are now in different places. I close the editor and reopen. Now things are back to the first time I ran the activity. Soooooo. is this a common problem or is it just me How close is the simulation playing to what the activity editor shows?Dan
Yes, you guessed right!! good old AE, RE, ahh.. good old MSTS for that matter..A lot of us have had those problems.. (or at the very least, myself).. I find I have to keep rebooting AE just to get an accurate reading.. Don't really know why there are such great discrepancies in the timing, every time you test it out..best of luck with it though, and another MP or MP3 activity would be nice! (I'm working on a few myself and possibly on KHP.. just to get back to contributing "something" here..) cdntrains"must be trains in the blood" http://www.frograil.com/gifs/gifs.htm
