CREO 7.0.6.0 Fatal error encountered

Hi!

I'm using Creo parametric 7.0 in the last few weeks, and I came across a new problem that I have never experienced in Creo 4.0. Running the application after some time, or some specific moves (hiding and unhiding framework elements one after another) the following message is shown on the screen:

And after that the program shuts down itself. I attached the traceback file as well.

I saw a topic which is about fatal errors in previous versions of Creo, but the solutions that they mentioned didn't work for me (open_gl_fbo ; win32_gdi ; graphics card driver upgraded). It happened one multiple devices, almost all of us uses it in our team. It's an educational license product.

Thanks for your help in advance!
