>This problem is driving me crazy - I have an old web project that I need to make some changes to. However, I have a couple problems: the first is that when I double-click on a web control (i.e. asp:button), instead of going to the relevant code-behind procedure, it jumps to the top of the asp.net page, adds a script tag and proceeds to add the proc there.

As far as I can see the page should be wired up to the code. Is there some metadata that could be corrupted? It simply doesn't act correctly...

You say this is an asp.net button but the behavior you are seeing is what I would expect from an HTML Input button.
Which is it?
