moving window x&y positions for accessibility

I am having problems with my popup windows poping up in odd places. I use DW4 and havent found an extension to help me with this, but when I use open browser window, the window that opens comes up in odd places for viewers, and some cannot figure out how to move the window to reach the scrollbars and so on. Is there any code that can help me with setting the attributes of the window like making it go to X&Y spots? or is it just random positioning depending on the browser? Thanks a bunch!
