I am new to Cisco packet tracer. I tried many versions of cisco packet tracer but encounter the same problem whenever I click on end devices like pc, laptop or cam.etc it jost shows black screen. If anyone knows the solution please help me.
Have you tried uninstall and reinstall or use a different version? I am not sure this is something that you can fix by change configuration on the sofware.
Is it PT on MAC? I think we had similar issue; something wrong with MAC OS; if similar post was not post here; then maybe on Cisco Learning Network; I would go to CLN PT forum to see solution or root cause
