Help with NSCursor, please...

[Frederic]

Hi,

I'm trying to display a busy cursor during a long task.
(For testing purpose, I used the IBeamCursor)
The only thing I managed to do is to change the cursor AFTER the task is
completed.
I there any way to force the update of the cursor?

busyCursor = [NSCursor IBeamCursor];
[busyCursor push];
[busyCursor setOnMouseEntered:YES];
[tv addCursorRect:[tv frame] cursor:busyCursor];
// A long task
...

Thanks is advance.
Frederic
