I know there is no easy solution but I would appreciate
any help you can give me.

Problem: A comments default pop-up postion cannot be
overridden. (If using show comment a position can be
specified for each individual comment so position is a
property of comment)

I'm well out of my depth but-
Is there a way to extend/customise the comment object
maybe using a custom class... or api call or.........some
how trapping/hooking the comment's pop-up event.

Can anyone point me in the right direction?

TIA

Ian
