problem with plot tool?

[Ashleigh Louise Wiseman]

Hello

Are there any known issues with the plot function in opensim 4.3? I'm trying to plot moment arms against joint angle, but there's a few issues:

1. If I move any aspect of the LoA (insertion, via point, wrapping surface etc) and then replot the moment arm, it will not plot. I get an error telling me that no such moment arm exists. I need to restart opensim to be able to visualise the change. Restarting the plot tool does not work.

2. If the above error doesn't exist, then the plot function will plot the original moment arm rather than the new moment arm, no matter how many changes I make. I can only see a new moment arm curve if I restart opensim. Restarting the plot tool does not work.

This happens on two separate PCs (both windows) with the same models. Any thoughts? Should I revert back to an earlier 4x version of opensim?

Thanks in advance for any help!
