EDIT2: 1.4.7 worked! But, for some reason, the file plays at a slow rate. The visual isn't fluid. It's quite "jerky"? Changing the input in the field on the right corner doesn't make a difference. EDIT: I tied out v.1.4.5 after receiving a recommendation by email. "Error: Object reference not set to an instance of an object." Same error message for different gif files. PREVIOUS text: I went through the tedious process of registering just so I could post this review. I got this app amoung many others on my win7 system. This was the only one that worked like a charm. The gifs could even be expanded in size unlike in other apps where the gif size remains static. Unfortunately this viewer does not work on win8 :( really sad. Had to settle with one of the lesser wares instead. I'm sorry but this means (-1) on the perfect score. PS: sourceforge, can't you guys let facebook/google+ users post comments rather than have us register here specifically?
