When dragging a window with tiny awt , the window sometimes jumps
unpredictably. This is more noticable on slow machines.

Reproduce by putting several tiny awt windows up with complex paint methods
all controlled by the same virtual java machine. Rapidly drag one of them
over the other two repeatedly. This is only somewhat noticable under Solaris
on a SS10, but it is quite noticable under Kona, which is currently slower due
to much of the system being written in uncompiled Java.

The problem is that TinyWindowFrame processes MOUSE_DRAG events relative
to the requested position of the window, whereas mouse events come in with
events relative to where the window actually is. When your event queue
starts backing up, these can be quite different.
