Pausing up-down scroller - Is there a limit to how many lines it will scroll?

[StickyLabels]

1) Script Title: Pausing up-down scroller - Is there a limit to how many lines it will scroll?

2) Script URL (on DD):
http://www.dynamicdrive.com/dynamicindex2/crosstick.htm
3) Describe problem:
I have a very long list of customer testimonials each separated by "---" that I have placed in our up/down scroller which seems to "break" (ie: the scrolling function no longer works and the whole text, including the opening {UpDownScroller} and closing {/UpDownScroller} is displayed). Up to about 233 lines displays fine. After that, it all goes wrong.
Wondering if there is a limit as to how many lines the scroller can handle, and if there is somewhere within the code that I can modify to accept more.

Thanks in advance. Cheers!
