If I pause my editing in Vegas and use another program for a while, such as browsing the web, or if the PC goes to sleep, when I resume editing often, but not always, the video preview fails to update the screen when I click Play. The audio works and the cursor moves but the preview monitor is frozen at the first frame. Yet if I drag the cursor or scrub it does change as it should. V15 and V17.
To get it working again all I need to do is open the Options/preferences and close it. No need to change anything. Any ideas whats going on here? Not a major issue but so anoying!
