since the last update, the preview window will only resize one time to a large window. after that double clicking on the preview window does nothing where double clicking on the preview window use to toggle between 2 predetermined sizes.
anyone know how to fix this and get the preview window toggle feature back?
. . . . get the preview window toggle feature back . . . .
This 'feature' was removed - IIRC with Video Pro X (VPX) 11
There are 2 ways to do what you require:
Toggle to full screen and back - use the indicated icon - you can also press the Esc key to toggle full screen off
Save window arrangements - arrange the preview monitors and other panels as required and select Window, Window arrangement, Save - give the layout a name and save it. The layout will be assigned to a Function key. You can save 3 layouts this way and toggle between them using the allocated function key - by default these will be F10 to F12.
