I have been using ACDSee as a photo viewer, to randomly display photos and gifs in a large folder. Some repeating gifs I've made of small movie clips. They play perfectly on their own in other viewers - but in ACDSee, theres a brief white flash, maybe one frame, when the Gif begins its repeat. And sometimes a hard black line appears, for one frame.

Not all Gifs do this, and the length of the Gif seems to not be important. Is there any setting I can apply in ACDSee to prevent this? Or encode my Gifs in a different manner?

Any help would be appreciated.
