>Description:
	I've noticed sometimes that when I let go of a window, it stays
	"stuck" to my mouse-pointer.  I also can observe this in
	applications with, e.g., scrollbars.

	I can *very* consistantly produce this error if I am moving the
	mouse with any rapidity roughly when I release the button.

	I can *very* consistantly avoid the problem by not moving the
	mouse at the moment of release.

	I've noticed it for some time, but only now have I been able to
	notice that it's related to moving the mouse while releasing
	the button.

	I do not recall ever seeing this on NetBSD/i386, but I don't
	run those machines on -current too much, so I do not know if this
	is port-specific.  Could be port-amd64 or kern, rather than
	xsrc.

	Here's a full dmesg, in case it helps:

	On my system, hold down a mouse button, and move the mouse
	while releasing the mouse.
