I believe this is consequence of the main versus secondary window paradigm in Windows Acc but figured I'd mention it anyway. There is no way I can close the main workspace and continue using the secondary workspace except to alter the opening preference and then close Acc and restart it.It would be nice to see this work more like Mac where you can in fact close all WS if you but still have Acc running.
I guess I should note that File -> Close closes the WS but the primary window remains. Attempting to close it will of course result in closing Acc.
