RHIDE use these functions but:

1) Or they are wrongly used (something is incomplete).
2) Or they doesn't work for the graphic modes used by Allegro.

I think Robert tested it in the same way I did: debugging TVision programs. In 
that case the routines work. For some reason they doesn't work with Allegro and 
I saw strange crashes when debugging Allegro and the mouse is on.

:-))), I normally use it, the problem is when you need to debug something that 
depends on mouse clicks. In this case the user can disable the mouse before the 
zone to debug.

The second is ideal ... but, you know our fingers doesn't respond to our ideas 
;-)))
