Missing PDMW check-in dialog

Hi there,

I usually work on three monitors on my Dell M4600 (left, laptop monitor in dock, right) with SW open on the left monitor.  When I undock the laptop and work on the road some SW dialog windows still want to open up on the left monitor even though it's not connected. 

At the moment I am having issues with the PDMW check-in dialog box going missing.  Other dialog boxes seem to work fine.

I have tried the nVidia settings and most of the other solutions in this thread: https://forum.solidworks.com/message/295189#295189 but none seem to work.

Maybe there's a registry hack as per this missing measure box issue?: https://forum.solidworks.com/message/159575#159575

If there are any SW employees watching - it seems this type of issue is not just a one-off.  Is it possible for SW to detect which monitors are present, and only render dialog windows onto those?

Your help greatly appreciated.
