Quicken Premier 2015 can be started from a VirtuaWin window, however, there is no output displayed on the screen.

Today I downloaded and installed VirtuaWin from the SourceForge site, so I should have the latest version.
In VirtuaWin, I am running 2x2 virtual windows. The only "customization" has been to enable Mouse Switching.

Starting Quicken Premier, either through the Start Menu or clicking on a tray icon, gives the same result. The Quicken start splash-screen displays normally, but the main Quicken window fails to display on the screen. It does not matter which of the 4 VirtuaWin windows I use to start Quicken.

I know that Quicken is running, because it is listed in the Task Manager, and because I can hover over the program icon in the Task Bar and see a thumbnail of the program display screen.

Any help will be greatly appreciated.
