One of the pains of using Visual Studio 2003 is the lack of multi-monitor support. If you feel the same way go here and give some feedback:
Recently I have been reading code from multiple files and was trying to refactor them. One of my monitors is 21" and the other is 17". So expanding the IDE window to both monitors would not work. It would be really nice to drag a code window onto the second monitor and now you can cut and paste whatever you want. Note that I said CUT and not COPY. I am not a fan of COPYing code!
