[flexcoders] Cut & Paste KB Difference between IE and Firefox

[aceoohay]

I have created a tree component whose only difference is to allow control-c to 
copy things from the tree to paste in another component. When I run it in 
firefox, it works fine. when I run it in IE v7 control-c does nothing.

Any ideas?
