Bugs in rightMouseDragged

[Jan Trembulak]

In my NSView I have the following method.

@interface MyView:NSView
...
@end

@implementation MyView

- (void) rightMouseDown: (NSEvent *) aEvent
{
    NSEvent *event;
    do {
           event = [NSApp nextEventMatchingMask: NSRightMouseDraggedMask
| NSRightMouseUpMask
                                   untilDate:[NSDate distantFuture]
                                      inMode:NSEventTrackingRunLoopMode
                                     dequeue:YES];
            NSLog (@"Mouse dragged\n");
    }
    while ([event  type] != NSRightMouseUp);

}

@end

I have 3 buttons mouse. When I dragging with right mouse button, only
one message (Mouse dragged) is printed.
When I dragging with middle mouse button, I got a lot of messages. (This
is a right function, but with middle mouse button).
In Openstep for Mach 4.2 this example works fine (with right mouse
button).

I test this example on RedHat 6.2, Solaris 2.8 with gstep-core-000709
(000730).
Do I something wrong ?

Thank you.
