RE: Re: [ToonTalk] Proposed changes to ToonTalk tools

Hi,

	I personally like this traditional solution, but I see a problem
with it: many kids (in fact, even a few adults) tend to slide the mouse a
bit between the press and the release. I have a few 18-year old students
that have to be careful when right-clicking because of this: they were not
used to right-clicking and the first few times slide the mouse in between.
	
	Another possibility would be to make the difference in coordinates
tolerant. I.e., dragging mode would only start if the mouse changed position
over, say, 10 or 20 pixels.
	
	But Ken's option is also quite acceptable, as long as the
sub-pictures wiggle as you point at them.

Inté,
 
Leonel

How about entering dragging mode if (any of the) the mouse coordinates
change while the left button stays down?
