I justr started having this problem.

Each time I open the program all the tabs showing exploere, etc are gone. Have to reset them.

And then after Vegas renders a file, the complete program closes down. And upon restarting the program a window pops up which states : "The Last session did not complete properly. And ask if I want to restore the autosaved version of the project...."

This happens with any file I try to render.

Have not been able to find how to stop this from happening.

Thank you,
Jeff
