Using the ReportViewer in a Visual Studio 2010 WinForms project. After updating client to Support Pack 12 after print previewing a report that has a ODBC connection to a text file using the Microsoft Text Driver the text file remains open after the ReportViewer is closed. Roll back to 13_0_8 which is what we were previously distributing and the text file and ODBC connection is closed without issue.
