Viewer displays wrong report when I drill down

[whyworry]

Error caught in ICrystalReportViewerImpl::render
When I run report1 and drill down it is correct. When I run report2 in a new window it is also correct. The problem is when I switch to report1 window and attempt to drill down again then it displays a 'catastrophic error', when I click the back button to return to report1, I get the data of report2 so both windows now show report2.

I have tried all sorts and now confused, the users are getting frustrated, any suggestion please?

Sounds like you have 2 viewers open in some Crystal based product, but not bothering to post the software used and the version wastes time.

It is CR ver9. The reports are called from ASP via CrystalParam.asp which talks to Report Application Server.
Many thanks
