TreadedPageCache exception

Any idea what could be causing this Access Violation while previewing a report?

Using RB 19.04, Delphi 10.2. Running Win10 on a tablet

Error is "Access violation at address 02229157 in module 'CC.exe'. Write of address 00000088."

Stack Trace is

Hi Martin,

This may be a conflict with the threaded page cache and another aspect of your application. As a test, try setting the PreviewFormSettings.SinglePageOnly property to True and re-run your application.

Thanks
SinglePageOnly = True has fixed it
