Hi All, We all know Win7 Explorer shows animated GIF files as static thumbnail previews, but I'd like a way to hover over one of these GIF files and pop open a full size (whatever dimensional size the GIF is) animation. My thought is to hook the window's tooltip popup event, and substitute a separate window scaled to the GIF file dimensions. Being a programming "dabbler" with little realtime experience, is a good way to start? I previously looked at AHK, but they won't won't let me sign up for their board and questions are definitely a necessity. Or is this something that already exists? TIA! Russ
