problem: vegas pro 14 buil 161: using a second monitor to show a clip fullscreen: result: black screen (second monitor).
normal quitting the programm not possible (shift-alt-ctrl thing needed)!
uninstalled, reinstalled, updated quicktime, updated to MS .NET framework 4.6.2.: nothing helped.

IMPORTANT: SONY MOVIE PLATINUM 13.0 (64 BIT) WORKS PEFECTLY! no problems with viewing on a second monitor.
