Hi Nimmy,
It seems to me that it would be pretty easy to reproduce the timeline
problems but I can see it taking a lot of time to do so if you didn't have
affected files already.
So I am sending you to identical slides saved as CP8 and CP9 files so you
can spot what is going on with the timeline.
You also might want to make note of the fact that the cptx files saved
between the two versions are different sizes even though the content is
identical.
Thanks,
Randal Perry
