Opens in Previous Extended Desktop Location After Monitor Orientation Change

[Ron Mellum]

The situation is that I use a laptop at multiple locations with an external monitor and extended desktop (not mirrored). One of the locations the orientation of the external monitor is to the right of the laptop and the other location has the external monitor above the laptop. With the monitor specified to the right, I open Filezilla and drag it to the external monitor. Closing and then opening Filezilla will cause it to open in the extended monitor. If I now close Filezilla and either change the relationship so that the external monitor is above the laptop or move to the other location, and then open Filezilla, the Filezilla window will open in the non-existent right hand extended desktop. In order to rectify, I need to to change the orientation so that the external monitor is specified to the right and then drag Filezilla back to the laptop. Other apps open in the laptop screen after the orientation change.

To reproduce:
1)using an external monitor specified as extended desktop and side by side, open Filezilla in the main window and move to external monitor.
2) Close Filezilla
3) Change orientation of monitors so that the external monitor is above main desktop.
4) open Filezilla
5) Filezilla will open in the previous location and cannot be seen.
6) change orientation of monitors to be side by side and Filezilla will be displayed.
