Is there any way to pre-define the size of new IE windows?

IIRC, it opens the same size as the last one closed. So open one, size it properly, then close it. The next one you open will be of the same size.

Of course, that means that you have to be careful with the order in which you close your windows when pop-ups occur, as they are usually of a much smaller size. Make sure you close them first (which can be a chore as they sometimes lower themselves under your current windows), but not the last one before you want to open a new window.

Wouldn't it be much easier to use a browser that incorporated tabs (Mozilla or Phoenix) or MDI (like Opera)?
