OpenSim 4.0 Beta GUI Issue with Scaling, Inverse Kinematics and CMC

Hi,

I am working with OpenSim 4.0 Beta in the GUI. Trying to analyze the GIL files (from https://simtk.org/projects/mspeedwalksims) by scaling, IK, RRA, and CMC to extract muscle activations at different speeds: xslow, slow, free, fast. When I scale using the XML scaling setup file in GIL01 and apply manual scale factors to the femur, tibia, and talus (these scale factors are not included in the setup file), the tool says "Executing Scaling" but never stops and no result is produced. I've tried this with the Gait 2392 thelen and millard models, the newest Gait 2392 Subject 01 model (from https://github.com/opensim-org/opensim-models), and the Hamner full body with simple arms model.

Is this to do with a problem in the models, the GIL files, or the GUI?

Thanks,
TG
