once the report opens in the browser (IE5.5) I can scroll page by page
without a problem, however an error occurs (sometimes) when I scroll
back (or goto a page) i.e. no results shown on the page (whereas
results were visible previously on first pass).  It seems to occur
after i have scrolled or moved to page 11, but sometimes 12, or 43 ...
limitation on number of pages or amount of data?

by blank, I mean the report page header,group header and page footer
display, but the results and subreport do not.

suspect it is not data related as it happens inconsistently e.g. on
one occassion pg2 will be blank, on another pg2 is fine but pg 6 is
blank.

does anyone have any ideas why this is happening and what a possible
solution can be?

thanks
