Microstation crashes when changing models thru project explorer

My Microstation is crashing when changing models in the project explorer.  

I have a problem switching between models in SS4.  I can switch once from default to a cross section layout but switching back to default or to another model crashes Microstation.

I can recreate this problem on other work stations in my office so its not specific to one computer.

It works fine while using the Models dialog (File Pulldown>Models).

Microstation 8.11.09.832

Geopak 9.11.09.878

Win 10 and Win 7

I have done the usual, checked the drivers, cleaned the system. I did have the "lock pages in memory" note in About Microstation under help which I fixed.

Is there any other suggestions?

Thank you
