[OpenLayers-Users] Initial question: Cannot display controls

[Xiaopeng Xiong]

Hello List,

I just tried the live demo at http://openlayers.org/dev/examples/click.html. 
It works fine.
So I copied the exact source code into my own html file. But none control is 
displayed well. You can check my html at 
http://www.cs.purdue.edu/homes/xxiong/OpenLayers/clicks.html

Did I miss anything here?

My another question is that what are the event names for mouse pressing, 
dragging and releasing?

I appreciate any help and suggestions.


Thanks,
Xiaopeng
