I am quite accustomed to using Dyamic RAM preview, however, I have noticed that recently when a select an area (about 100 frames) and press shift+B, it will render about 3 and then stop. This has only been happening recently, so it may have been a setting I have accidentally changed, but I am not sure what. The RAM preview is still set for half of my total RAM, and my RAM monitor program assures me that while the dynamic preview is rendering, my RAM only drops about 5 megabytes and then the render stops. I still have plenty of RAM left! So, I am quite confused.

Thanks for helping.

Edit: Well, huh, if rewind all the way to the beginning and render from the beginning up some it works fine now.
