I've just opened a completed render (1900x1200), to discover that approx 1/8th inch along the bottom appears as an unrendered white bar - any ideas what caused this, and how to avoid this happening in the future?
Other settings: Quality 4000, Filter Radius 0.2, and Oversample 16.
I'm kinda annoyed about it as the image was going to be a one-off render to a friend, and as such I wasn't going to post it.
Edit: I dunno if it's relevant, but my screen res. is 1600x1200
