Non-modal mouse tracking (alias executing services within a mouse tracking loop)
has at least the following problem, I guess:
You cannot be sure that the view is unchanged while you are
tracking the mouse. Everything may happen including moving or closing the window,
updating the view contents the mouse is moving over etc.
This would significantly complicate all peaces of code that
use modal mouse tracking now.

As a simple workaround I could imagine to provide
a global hook within Ports.Frame.Input() (or some similar central place)
that allows one to extend any mouse tracking loop by application specific code.
It would then be the application developer's task to ensure that
there is no change of any data structure that affects existing
mouse tracking code.
If there is for example some data aquisition into an internal buffer being done
in this hook, the text or form controllers or whatever mouse tracking loop
would not notice that and would of course work as before.
