Perhaps this is the incorrect location for this request but I could not locate a thread for the WHDS. I want to create a data view to support the WebDataTree from an Oracle database. After configuring a new datasource the "Test Connection" yields positive results but clicking the next button to write connection string to the application configuration file sends the dialog off into etherspace.  The write never completes and doing ANYTHING else causes VS2010 to grey-out and the only recovery is to kill VS2010. I have refreshed the installation of both VS2010 and NA2011. Same problem. I have tried it wiht both Oracle and OleDB connections. Same problem.  My hair is turing grey. Any idea why this is happening?
