A quick followup.....

I loaded the rcc from a backup disc into my laptop (which has the 'old' software) and the GIFs ran perfectly. Loaded the rcc into my desktop and the GIFs malfunctioned as mentioned in my first post. As a final test I just loaded the rcc into a third computer (which had the old software) and it worked perfectly. Then updated the third computer with the new software, re-loaded the rcc, and BINGO, the GIFs malfunctioned. Don't know what the problem is, but I'm certainly not going to update my laptop's software until a fix is found.......
