DataPresenterExporter seems to hang for upto 5 minutes on 32 bit machine but works fine on 64bit windows 7 machine.

this is the call which hangs:

dataExporter.Export(grid, filename, WorkbookFormat.Excel97To2003);

The sheet does eventually get created after a long long time. 

However it works fine when I create the worksheet and workbook separately.

var workBook = new Workbook(WorkbookFormat.Excel97To2003);
          Worksheet worksheet = workBook.Worksheets.Add("Results");
          dataExporter.Export(grid, worksheet);

Any ideas?

Also, to add that this approach was working fine until I upgraded to Infragistics v14.2 from 11.

Thanks
