Im seeing this same behavior in IE 6 (verified it in IE 7 also), and as usual FF is working fine.
It appears that the key listener keeps working, just the dialog is not the focus anymore.
I setup a test page, the 'a' key is attached to the dialog, and the 'b' key is attached to the body. The 'b' key continues to work after the dialog is moved, but the 'a' key does not. http://www.vinylfox.com/yui-ext/sandbox/test4.php
The dialog can only receive keys when it has the focus. I will add a refocus to the default button or the hidden focusEl after a move or resize in the next rev.
In the meantime, tell me if this workaround fixes it for you:
I updated my test page with those two lines and everything appears to be working as expected.
Also, I noticed while playing with it before adding those lines, that if i clicked back in the body area of the dialog that my keyListener mapped keys started working again.
Ext rocks.
Using Ext2.0.1
