How to make java based menu open links in new browser windows?

How to make java based menu open links in new browser windows? I have the code below (simplified the number of menus displayed) with menus for download MDAC and .Net framework 2.0. Currently all links open in the same window which is fine in some scenarios but not in others.

So lets assume that MDAC should open in the same window (which currently works), but I want to open the .net framework download link in a new window, how do I achieve that? I can modify the rest of the menus myself (something like 30, and modify with changes as needed).

I'm assuming that the code in the writeDrop function needs to be modified? Please include a code example and description on how to add that functionality.
