	It sounds to me like you have a bug in your processing loop (this is

	Why do you set RELVERIFY?  I set just FOLLOWMOUSE and GADGIMMEDIATE
and it works great.

>Also, beware of quick buildup of MOUSEMOVE messages.

	A way around that:
--------
	while (msg = GetMsg (window -> UserPort)) {
		class = msg -> Class;
		ReplyMsg (msg);
		if (class == MOUSEMOVE)
			moveit = 1;
		:
		:
	}
	if (moveit)
		movethedamnthing ();

	Good luck, guy.
