Visual Studio 2005 bug in ASP.NET applications

my web.config has multiple connection strings.
when I right click on a table adapter in a dataset in design view, select "configure...", the dataset configuration window pops up. Naturally you'd just make the changes that you want to the query and click on Finish. If this table adapter doesn't use the first connection string listed in the web.config, visual studio will automatically change the connection string to the first one listed in the web.config.

In order to fix the problem when you first open up the configuration window click on Previous to go back to the connection string selection view, RESELECT the connection string. If you happened to encounter this error until this stage right click on the empty area of the dataset design view and select View Code. Then delete the unused connection string.
