kewl thanx for that...It all worked except for one prob... The popup 
menu needs the location of the mouse click so that it can show the 
menu in the right spot... How would I get the mouse position.

Also I need to recognise double click events...How would i do 
that???

Thanx

Using the setLightWeightPopup(false)
worked fine...

Thanx all
