I had the same problem,but I recently figured out that you don't have to click 'Browse' as long as the picture's in the clipboard.GREAT PLUG-IN Pyrochild!
I'm LOVING this thing,but when I want to resize it,or flip it,it flips or resizes the whole layer.I can't make a sprite movie like this.HELP!!!! :!:
P.S:Yes,I highlight what I wanted to flip/resize.
