      Description

      The dashboard applet provided by speed-trap.com does not launch with the new Java Plug-In because of overly aggressive heuristics that filter out bogus calls to the COM method SetObjectRects by the Internet Explorer browser. This is a problem that has come up a couple of times before in the development of the new plug-in: see for example 6627606. Unfortunately the reason the old plug-in works appears to be due to subtle race conditions in the old plug-in's startup sequence which have been categorically fixed in the new Java Plug-In. Fundamentally, when SetObjectRects() is called with a zero-sized rectangle, we need to know whether it will ever be called again at some point in the future with a more valid rectangle.

      See the Comments section for the test case.
