I have seen this problem in builds 447 and 458. If I use CTRL+Click or double-click to select text and try to edit the selection (using Backspace, Delete, or just typing over it) Visual Studio completely freezes on me, forcing me to kill the process and start it back up. I don't think this problem showed up until I installed VSWindowManagerAddIn2005, but once I uninstalled R# it went away. I am using VB.NET 2.0.
Any solutions to this or is it a bug that needs fixing?
