ok started playing a bit with popup so I can try it...in addition to my normal popup menu I have this:

in xLabels.rx:
pl1_buttonOnLeftClick !Popupplaunch

*Popup "plaunch" !new !popup plaunch
*Popup "Test" "!alert 1"
*Popup "Normal Entry" !alert "my quicklaunch entry"
*popup ~new

Nothing ever shows up.
