Make a custom workspace just for one monitor.
I'm sorry, I guess I don't understand how this helps. If I have a two monitor layout and my second monitor disconnects, Premiere doesn't switch to a single monitor layout, it just rearranges my two monitor layout for a single screen. Even when my second monitor gets reattached, the two-screen layout is now a single screen layout. And I have to reset up all my windows again.
Are you still experiencing this issue or have you solved it? Please let us know.
Still experiencing this issue. Basically, if my second monitor gets disconnected I have to re-align all my windows for my 2-screen layouts when it comes back online.
My current work-around is to switch to a single window layout before the monitor disconnects, and try to only start up Premiere when my second monitor is connected, but sometimes my computer goes to sleep when I'm AFK and I just need to spend a few minutes resetting things.
I also have this issue - being as I work both in office and remotely - it would be nice if the entirety of CS could be smart enough to at least know what i've selected a specific monitor setup, if not detect it and quit shuffling toolbars around.
