CS3 Save As .Jpeg Program Error

Question

When attempting to save an RGB or CMYK file larger than 100M as a jpeg, an error message appears stating "Could not save a copy as C:(file name) because of a program error". Two questions:
1. Will resetting my prefences affect this error? If I try resetting my preferences, will my custom color swatches and patterns be erased?
2. Is there a known solution to this error?
Thanks...

No, not really. The failure here is that PS simply assumes it has always enough RAM/ memory under any conditions and then it runs out because obviously for a 32bit app the ceiling is and will forever be 4GB (if run on a 64bit host OS like XP64). it is also further complicated by the fact that you never know how much more RAM you need until you actually have built the block pyramids for compression. Theoretically you could still have enough juice even with large images if only there pixels are distributed in such a way that they generate an "ideal" block pattern. So there you go. I guess this once more illustrates that such optimization and analysis features should be a native core function rather than plugged on in the loaders/ savers...
