Sometimes when I get back even after a short period of time to my notebook, all RD windows are just black. You cannot do anything except turn them off and reconnect again from the menu. The notebook did not go sleep, only the Display go blank. I might have some connection breaks from tim to time, but that's not sure. I get it more times than connection break due to network errors. Sometimes the reconnect button comes up, but sometimes nothing, just big backness.
