I'm running Communicator for Mac 13.1.0 with a corporate account. Whenever I attempt to screen share it *looks* like it is about to work initially but then the screen sharing drops out after a couple of seconds. After the screen sharing session drops out I see "an error occurred" in my conversation. The same happens if someone else shares their screen and I try to view. Any ideas what I should look for in resolving this? Our corporate IT doesn't formally support us Mac types unfortunately. Thanks much for your help.
