I use a Laptop and an external Monitor (in the office). When using modeling and model manager, i often move windows to the external monitor. Unfortunately, when i restart my laptop without the external monitor (home/site), the Model Manager window(s) is no longer available as it is trying to dock to the now non-exisitant location on the external Monitor.
There is a semi-workaround regarding the MM window - "Shift+RMC on the icon in the task bar -> Maximise" - will allow you to access the MM window, but unfortuanately this is not the case for the load window.
My product reqeust is for MM to identify when hardware is started on single or multiple windows and to always be visible regardles off how the application was shut down.
