I use Vue 5 Infinite, and everything has been just fine until recently. For no apparent reason I can think of, I have noticed that when I go to render an image, whether it's a preview render on screen, main view, or a full render to hard disk, I am stuck there until the render stops or I stop it. I can't go do anything else on the PC. Even if i already have other windows open, I can't use them. It's like Vue has taken control until rendering finishes. 

Has anyone experienced this or know what is going on?
