Bug: enh VS2012 client: change bindings

[Mordachai]

In the Enhanced vault client for Visual Studio 2012, if you use file, vault source control, change bindings, then click on status column (to sort by status), that dialog disappears (presumably due to an exception internally).

NOTE: just try clicking on a header and then another header. sometimes it doesn't crash the first time, but by the second time I click on that particular column header it always crashes (for me).

Thanks for the report. We'll see if we can reproduce this here.
