Parameteres missing when rolling back on a subreport.

I'm developing a web service using VB.Net with SQL Server Reporting Services (SSRS).

This is the software i'm using:

• Microsoft Server 2003 Service Pack 2
• SQL Server 2003
• Visual Studio 2003

It's working fine on Internet Explorer but I'm missing parameters or credentials when i do a rollback from a subreport and I go to a different subreport on Chrome or Firefox.

Example: I go to a report called Client Sales and then i click on a client name. Then i click on a client payment and it gives me to the subreport ClientPayment.

I do a rollback, and goes back to the client report, and i do it again for going to Client Sales. After that, I click on a different client, and appears the following error (without printing the subreport, of course):

Some parameters or credentials have not been specified

Have you ever experimented this issue?
