UPDATE: Yeah it's not letting me add sprite sheets at all. I can insert new object, add sprite, but when i go down to the Animation Frame window and right click to add new sprite sheet, every thing is greyed out except Thumbnail Size. I click on it anyways...it still opens up the window to browse folders to add a sprite sheet. But when i do the whole thing just goes ape sh*t. It freezes up and when i click anywhere on the screen it just makes a ringing sound. I don't know if it's something i did, or it's a bug. But i do know it's super annoying.
