Saving Animations And Security Feature

I work in different 3D programs and I have never had this problem before, and it only happens in Vista. When I create an image, my programs create the image, and I can save it with no problem. When I create an animation, the programs need to save the file after it creates each frame. Vista is blocking those programs from doing
this, and I need to have them allowed to create and save these files constantly. I like the security that Vista has, but is there any way to allow just certain programs to do this while keeping that security feature on for everything else?
