[H] Can't view https pages in IE6

[Thane Sherrington]

For some reason, my IE6 has stopped wanting to view https pages - so 
I can't login to www.gmail.com, for instance (I get a page cannot be 
displayed.)  Firefox works fine.  I've tried clearing cookies, 
history, temp, with no change.  Reset security settings.  No 
change.   Any ideas?
