Hi,

I have created an animgif showing a countdown from 15mins to 0mins (at
the moment just testing with 15-10 at 5 second intervals).

I have placed this on the master and made half a dozen slides.

When I start the slideshow, the countdown gif starts its job, but when
I advance slides, it jumps back (not necessarily to the start of the
animation).

Can anyone help?  I need to get a timer to count down as accurately as
possible during a presentation.  If not this way, is there another
solution/workaround?

Many thanks
