report type flashpaper

I created a couple of reports and try to run different format.

I just realized that some report works flashpaper, but some of them do not.

I set default format to flashpaper at design time for all reports.

The reports work for PDF, Excel, RTF, XML and HTML, but for flashpaper some of them work, some of them do not.

I would like to know are there any property and code need to set it works.

I use IE 8 which should support flashpaper, since some of the reports work.

Your help and information is great appreciated,

Regards,

Iccsi,
