I agree and disagree with the original statement. Filter Forge should stay on the Mac. However, it has always been unstable, and crashes more than once a day. I've given up reporting this, it's usually when I'm editing a filter, typically when I exit the editor and return to FF. It has been insinuated that there is a known memory issue on the Mac. If so I'd love it if FF could fix it. In some ways the product feels home spun, and I suspect that Windows is supported better than the Mac. My 2 cents.
Math meets art meets psychedelia.
