Disable an "Ok" button in a dialog.

Disable an "Ok" button in a dialog.

Hi all,
I'm using jQuery UI v1.6rc2. I know this is an old version, but for
now, I am unable to upgrade. I have the need to disable a button on
the dialog box. I've tried just setting the disabled attribute via
"$button.attr('disabled','disabled')". However, on IE, that looks
bad. And on Firefox, the button can still be hovered, making it look
like it is enabled. Is there a way to do what I'm looking for?
Thanks,
Tim
