From a Javascript function I launch a window.  In that window I wish to 
gather some info, change some info back on the parent, and then return to 
finish the rest of the Javascript function.  I can not for the life of me 
get the original Javascript function to wait for the child to be done 
before continuing.  Do I need a special parameter in the call to open the 
window to have it wait until I am done?  Thanks.
