streamwriter xml doesn't parse until resaved in notepad

[markofsoton]

Hello got a bit of wierd one, and i think its probably to do with encoding

i have inherited a application that should write some xml for a domdoc application, the output looks valid but IE insists the top level element (noteTypeAbbrv) is not valid. if i tke the file ans resave with no changes in notepad then the file parses fine if the domdoc app and ie...

anybody got any ideas

thanks

Mark
