Help!
I have a PROTOTYPE called lamp. It has three rotation points:
The LampShade
The FirstArm
The SecondArm
Anytime these rotation points change, I want to inform my
applet.
The Problem:
I am not informed of all three events. It will only informs
me of one of the three. Usually, the first part of the lamp
I rotate will be the event sent. The other events are ignored.
Attached is a short WORKING example of the problem.
Any help would greatly be appreciated.
