Is there a limit on the number of windows I can open?

Martin Honnen,

Yes, NN4 (I am not sure about earlier and later versions) has a 
documented limit of 100 windows "to be around at once". With your 
standard web site that should be difficult to reach but there have been 
complaints of people building browser based applications running over a 
period of days or weeks where the limit was reached. The docs claim 
that setting
  window.opener = null;
for a window whose opener window has been closed is necessary to get 
the closed window garbage collected (and out of the count of used 
windows I understand).
