Issues with the object of Telerik.Reporting.Chart ChartMarkedZone

[Cris]

We are having trouble adding more than one ChartMarkedZone object in a chart implemented in a Windows Server 2003 and therefore with IIS6, the messages from a error says something like "Attempted to read or write protected memory. This is an indication That Often other memory is corrupt. "or else "A generic error occurred in GDI +"
This problem does not occur in IIS7 but we can not force the client to update the version of Internet Information Services.

Hi Christian,

Unfortunately we could not reproduce the error on our end with the provided code, but we have a suspicion.
Generally such a problem can be caused due to the limited stack size of IIS (250kb) while the Casini server has a higher stack limit (around 1MB) and that is why it works locally. Try increasing the IIS stack and also after researching on the problem we found out that setting Enable 32-Bit Applications in the ASP.NET's application pool should also have an effect so you might try this as well.

If the above do not change anything, please provide us with a runnable project that exhibits the problem under IIS 6 and we would be able to advise you.

Greetings,
Steve
