If an action is a bit sluggish then it's not obvious that something is happening

In IE6 especially it can take several seconds from clicking an action to something actually happening. The user should have some kind of feedback that their action has been registered. I have a couple of ideas which may help this:

• Change the mouse cursor to "wait" when the client is busy
• Flash, or otherwise make the action icon do something to look like it's been clicked. Could even play the click sound, but that my not be good for people in an office environment.

Ideally it would just be really quick to perform the action, but performance in IE6 is a bit of an issue at the moment.
