Opening a 2nd browser window

I know little about WEB browser programming.  A have a net.data macro which 
searches an Iseries Indexed file for a particular Engineering drawing, named 
like S0W538_20060526.pdf.  The user can do a partial or generic search, and all 
the candidate drawings are presented on the 2nd screen.  The user then clicks 
on the drawing desired, and the drawing loads up in the Acrobat Reader window.  
The users have asked me if I could figure out how to have this Acrobat Reader 
window to be a separate browser window so that when they X it out (close the 
Acrobat window), the previous browser window will re-appear.

I'm not sure how to do this - maybe there is a better way?

Thanks,
Don
