Comment (by cypherpunks):

 Btw, I think kludge should to check negative value of delta_fix:
 {{{
 if (delta_fix <= 0)
 }}}
 instead of
 {{{
 if (delta_fix == 0)
 }}}

 And as every kludge, after:
 {{{
 delta_fix = Math.floor(diff_height / 2);
 }}}
 Rounding or proper placement of window can to fail in result if user
 changed browser's toolbars in some way, removed, resized, etc.
