Just upgraded to ASPRunner 6.1 build 2503 from ASPRunner 6.0. I regenerated my pages in the new version. The detail page does not display correctly in Firefox (3.0.10). The table runs off the page. It works fine in IE 6 and IE7. Everything was fine in ASPRunner 6.0. The page formatting stops but the record display just keeps going. This happens for any amount of records per page except 20.
I recommend to post your application to Demo Account (use 'Demo Account' button on the last screen in program). Then open a ticket at http://support.xlinesoft.com sending your Demo Account URL for investigation.
