Next: onfunction and offfunction - I understand that it defines an action for mouseover and mouseout. I assume that this is in "addition" to the normal menu expansion on mouseover?
At least it does appear to work.

Problem that comes up, is the "tip" displays BEHIND the sub menu, and also becomes a "sticky" tip, even though the offfunction is a call to the "clear tip" function.
Any suggestions for a fix on this one is appreciated, as well as an explanation on the "targetfeatures" as listed first.
Regards,
Rand
