Multiple instances of CRReport??

[Patzer]

Hi out there,
I'm facing a very strange problem concerning multiple instances of the CRViewer Object.

I have written an app where I open a CRViewer Object. This report contains several SubReports

Usually the user clicks a menu and one report instance opens. But under certain conditions up to 4 reports should open.

For the first object everything is ok, data are displayed correctly.
But all the other reports don't seem to be able to correctly display data from the subreports, all subreports are empty.

I've set the discardsaveddata flag true, but that did not change anything.

CR is version 8.5, data are called from MS-SQL-Server 2k

Any ideas out there? Is this a bug in CR? This is very urgent so PLEASE answer
