I created an exe file recently using PTE v5.1, with just the fade in/out transitions. One person reported problems she described as 'flicker', which was so bad she couldn't watch the show. Nobody else has this problem. I believe her PC isn't all that new, but probably bought in the last 3 or 4 years. Are there any minimum specs for viewing PTE exe files (as opposed to using PTE itself), e.g. graphics card, RAM, version of DirectX, etc, and is there anything I can do to alleviate the problem for her, such as switching off hardware acceleration? Thanks
