[Chameleon] Unable to close ROI polygon

[Yahya Mohammad]

Hi all,
I've set up chameleon inside an iframe in my application and everything is 
working well, except for the ROI polygons. Apparently the onkeypress event is 
not being captured by the frame, so I can't close the polygons. I can make it 
work by hitting TAB a few times until the browser focus moves to the iframe 
and then the polygon closes. 
Since I already clicked a few times on the map to define the polygon vertices, 
shouldn't the focus already be on the iframe?
Is there a way to focus on the iframe using javascript when the polygon ROI 
tool is clicked? 

I'm running Firefox 1.0.7 on Suse 10.0

Thanks for any help
