Render, Preview Window and Match Aspect Ratio

Dan Sherman wrote on 9/23/2013, 6:58 PM
After working for a time in an instance of Vegas Pro 12 (build 714) the tool bar at the top of the window disappears, leaving a black rectangle.
I open a new instance of VP and paste in the project,....all's well.
Then after a while the tool bar disappears and the project window is again a black rectangle.
Also, all of the "Match Aspect" ratio work I have done (there a quite a few photo) are lost.
This project is finished and ready to render.
I thought I'd giver it a go, even though the project window was black.
You guessed it, the project shows up rendered as 209,970 KB, but on play back, it is black with only the audio.
I am in desperate need to get this done as I have promised it to the client tomorrow, it is part of a professional award presentation.
Anybody, please!
What the hell is going on here.

OK, I've sorted some of this.
I did a right click on the preview window and got the toolbar, status bar and transport bar back.
But I didn't deactivate them.
Default Background is checked as is
similar Device Aspect Ratio
Show status bar and
show transport bar.
But there is nothing IN the preview window, is a black rectangle.
Which makes no sense as there are images on the timeline.Oh dear,...

Everything has inexplicably returned to "normal".
I am rendering.
I still have no idea what happened here.

Build 714 was the problematic Build that was replaced after just 1-2 days by Build 760. You might want to install Build 760 and see if some of this weirdness goes away.

B 714 is the latest, replacing the problematic b 710.
