Hi Kevin-

At present there is no way to do this at present without writing some
code.  However, we are going to be working on some IDV enhancements for 
the upcoming RICO field project for plotting aircraft tracks and
this would be a good addition.  Do you have some sample files I could
use for testing?

DOH! My fault. Somehow this got past the testing.  I fixed it and it
will be in the 1.2 beta 1 release (sometime in the next month).

I can confirm that I see the same thing, but don't have a quick answer.
I'll have to look into this further.

>You guys are doing a great job!! I use the software more and more.

Glad it is working for you.  Thanks for the feedback.
