[Opensimws_apr10-news] Model not showing up in GUI

Tue Apr 27 00:29:32 PDT 2010

Hi again,

I now have a problem with the visualization of the model in the Tug of 
War example...
I could compile and run step 2 of the tutorial, and got the executable 
to produce a model.
However, when I use the GUI to open the tugOfWar_model.osim model, 
nothing appears.
Other models seems to load fine.
The model produced by the executable is reported below...any hint for 
trouble shooting will be wellcome!

Thanks!
Michele
