I'm sure I must have missed something.
I'm using Win11 Pro, Vegas 21 Pro build 315,32GB mem, NVIDIA GeForce RTX 3060, AMD Ryzen 5 7600X
I have tried the ctrl shft while starting which did what it is supposed to do but it didn't fix this problem.
I have been working on a video showing side by side video but it started to prevent me from getting a Full Screen Display when I restore in pan/crop.
I removed the other video from the time line and turned off the FX picture in picture I was using to get the split screen effect.
Here is a combined screen shot.
Hope someone can spot my error.
Thanks.
