</div>I'm not sure if this is what Bill is getting at, but there is a<br>
problem with just unconditionally triggering motion bindings. If<br>
you're moving or resizing a window and move the pointer to the corner,<br>
you don't want to make that trigger an expose effect or such.<br></blockquote><div><br></div><div style>That's true, but it doesn't require any client intervention, and it can be easily dealt with by the shell. Possibly by the shell only: not sending the binding when e.g. there is a pointer grab active would mean that having a popup open would inhibit the binding.</div>
