Hi everyone,

I have an issue with RobotStudio (either 32 or 64 bit, 6.00 or 6.02): When I’m simulating some station with complex movements and layout - clicked Play Simulation -, it freezes up at some points.. I mean the simulation time and robot movement freezes up and doesn’t continue until simply I slightly move the mouse over the screen, and the simulation continues like nothing happened.

It is not a major problem, I can still work with that.. but It’s really annoying when I want to record a 5-minutes video or viewer, and I have to be aware, seated around 15-20 minutes or more, in front of the screen just moving the mouse so that the simulation will not freeze; instead I confidently leave the pc rendering the .exe or video, and go to lunch or attend another issue/project.

Anyone else has happened this?? Does it could be a PC graphics card topic? Please tell me if anyone has solved this, or if in principle someone has this happened I comment.

Thank you for any suggestions/comments/solution :smile:

Best Regards,

Pablo Liberona
