[Javascript] Suppressing mouse-over events

[Håkan Magnusson]

This smells of IE specific stuff to me, but I'll give it a shot anyway. :)

Have onfocus and onblur-handlers on the window that contains your menu, 
setting a variable (bFocus = true/false) when the window focus is 
changed. On the onmouseoverevent all you have to do is check the bFocus 
variable. If it's false, then your window is out of focus, so don't 
display the menu.

Makes any sense? :)

H
