    return true"
    window.alert('Nej! Flyt ikke musen v&aelig;k - Tryk p&aring; det link!');
    return true"
    >Home page for Finn Theodorsen</A>

First the shown links are chosen in order.

Action			Expected behaviour (as in NS4)
move over, then away	Alert pops up and can be dismissed
move over, shift focus
  away with SHIFT+TAB
  and back again with
  SHIFT+TAB		Nothing happens
move over, select	Chosen URL comes up, no alert

Action			Real behaviour (Mozilla5)
move over, then away	Alert pops up and can be dismissed, but window 
                          refreshes at previous link (#extern)
move over, shift focus
  away with SHIFT+TAB
  and back again with
  SHIFT+TAB		Alert pops up, Mozilla crashes or freezes, lots of
                        memory is consumed (some eternal loop of                           
			  might be in progress)
move over, select	Alert pops up, Mozilla freezes, URL doesn't
			  come up. (same as above might be going on)

In both these last cases the alert-window cannot be dismissed, and the
only way to get onwards is to kill the job or wait and let it crash.

Part 1, where closing the dialog pops up the wrong window sounds like a dup of 
bug 22658.
Part 2, the crash after SHIFT+TAB I can't reproduce with a debug build from 3/7

I can't reproduce the freezing or crashing either now.
Also alert doesn't pop up upon choosing the link anymore.
Alert still pops up when you use shift+tab and now immediately,
ans the alert window takes focus.

Build ID 20000031516 (nb1n M15 of 16-3)
dsr_ft@dansk-sygeplejeraad.dk - could you summarise the issues this bug is still 
tracking, if any?

Action 			Real behaviour (Mozilla5)
move over, then away 	Alert pops up and can be dismissed,
			but window refreshes at previous link (#extern)
			(I believe this one has its own bug-number already) 		
move over, shift focus 	when focus is shifted to other page, alert pops-up
away with SHIFT+TAB and (immediately if to other NS window, otherwise upon
back again with SHIFT+TAB second use of SHIFT+TAB even though mouse is never
			moved away from link) in NS4 alert never pops-up!	

move over, select	no alert, functions as NS4 now

So the only thing that is left here is a onMouseOut event upon focus shift	
for all I know that might be the right behaviour, and NS4 that is in error
