I'll take it out for a real spin this weekend, but the patch has made things much happier so far. Do you find the interface slow? YES. Do you find the program taking a pretty long time to load? Longer than I'd like, but I'm impatient. Realistically, about 1.5 times longer than Adobe Photoshop. Do you find the rendering in Firefly sometimes cutting the head off Victoria, Mike, and even that funky looking Judy? Nope. Do you get those c exception errors? Nope. Do you find the FF rendering a bit too time intensive ??? Nope. do you get render lockups? Knock on wood, no. Does your library take a nap while it loads different subdirectories? It thinks about getting a tea break on occasion, but it's not bad. It's mostly when I have some .rsr files that need to be converted. Dell 1.7Ghz. 512MB RAM.
