What is up with the Microsoft VS IDE?

I've been using the VS IDE to program in asp.net after using webmatrix to begin with. I'm strongly considering returning to webmatrix though. The reason for this is that every time i go into the visual designer, I make a few mouse clicks - resize/move something whatever; and low and behold - the VS IDE replaces a lot of my tags with their namespace!?
i.e before the changes, the tag is <IE:Tab text="Tab1" /> after the changes it is <Microsoft.Web.UI.WebControls.Tab Text="Tab1></Microsoft.Web.UI.WebControls.Tab>
this causes errors in the rendering of the controls. It is really infuriating, and if Bill Gates was here right now, I'd clock him one :p

I have been experimenting with the Microsoft.Web.UI.Webcontrols collection. I place the following at the head of my page:

<%@ Register TagPrefix="IE" Namespace="Microsoft.Web.UI.WebControls" Assembly="Microsoft.Web.UI.WebControls" %>
<%@ Import Namespace="Microsoft.Web.UI.WebControls" %>

I also have the Microsoft.Web.UI.Webcontrols.dll file in the bin directory of my site... I also added a reference to this file as it didn't seem to pick it up.

Thanks for reading :wave:
