this will take longer than 2 days since it will require supressing the gecko
event system that sets the cursor and i'm not sure how to do that.

This is the first I've heard about this issue. Can someone summarize it for me? 
Adding joki to Cc since it sounds event related

Basically the issue here is that we need a way to set the cursor on the window
and have it not be changed by various parts of layout.  For example, if I start
loading my mailbox in mailnews, I want to set the window's cursor to reflect
that it is busy.  I don't want the cursor to get changed to something else if I
mouse over a link in the sidebar or some other area.  Any ideas?

[troy]

I see. Sounds like we need a way to tell the event state manager (perhaps) that 
the state is that the app is busy and the busy cursor should be displayed. We 
would need a way to tell it that the app is no longer busy as well

Tom, what do you think?

Okay, per my earlier discussion with pavlov we were unable to accomplish this 
feature using style alone since we would have to set the cursor style on every 
element and then change it back.  This is because the cursor attribute is 
inherited so if we set the cursor on the document using style any lower level 
element which specified its own cursor (as we do for elements in ua.css) would 
override the desired cursor.  So instead a method was added to nsIDOMWindow.  
The method is

SetCursor(in DOMString cursor);

This method takes any of the cursor strings specified in the CSS2 spec and sets 
the cursor.  This method overrides the cursor change as it moves about a page 
and only works within the bounds of the page.  In order to reset the cursor to 
allow it to change normally as it moves the cursor must be set back to 'auto' 
using the SetCursor method.
