OK, thanks. You and dob are right -- sorry for the misunderstanding. But it still won't work. I changed the line to read: <pre>dragColumns[i].firstChild.firstChild.addEventListener("mousedown",function() { this.startColumnDrag()},false);</pre> Which gives me the error: "this.startColumnDrag is not a function." I presume this is because of the "this", and I don't know how to get around this. As I said, I just don't know enough javascript to do this by myself -- which was why I posted this in the "ideas and requests" forum rather than the "script development" forum -- working on the principle that if someone who knows what they are doing thinks it's a good idea and worth doing, then they will. If not, then so be it. I really do appreciate all your help here, but I don't think there is anyway I am going to be able to hack someone else's 200+ line script to work in greasemonkey, without either dedicating a lot of time and effort to (re)learning javascript -- something I don't really have the time to do -- or wasting other peoples' valuable time here walking me through the code line by line. I've written a few short greasemonkey scripts, without too much difficulty, but this is just way beyond me at this moment in time. <p>OK, thanks.
