First off, I think your problem is how your first window is opening.

I've tried it both ways -- opening the first window maximized, and also opening the first window as a normal window.

Either way, opening the subsequent windows (by right-clicking on the thread and then typing "N" for new window) causes the new windows to open up where I don't want them. Except that sometimes, for a day or two maybe, they will open up where I want them. (Where I want them is defined as being anyplace other than top left of the screen!)
