For some reason, starting (I think) with 8.3.20083.2059 I've started getting an xml exception when trying to export a grid.

I'm trying to identify the cause but so far I'm stumped as the code that I have to build the report has not changed and the exception appears to be down in the bowles of the export function.

Has anyone seen this error before and have a suggestion or is there a way to capture whatever xml file the text reader is trying to read to see if I can find anything out from that?
