Hello,
This might be a common experience (or a well-known fact) among GIMP
users. I just want to say that I just recovered from De Quervain's
disease after an intensive week using GIMP. I'm not familiar with
the new versions of this software, but mine requires keeping both
my thumb and index finger pressed against the mouse while painting
and retouching pictures. I did this for 4-5 days, 3-4
non-interrupted hours a day. I ended up with a strong pain in my
wrist due to the inflammed tendons at the base of my thumb (De
Quervain's disease). My right hand was practically inoperational
for 2 1/2 months. A corticosteroid injection and a constant routine
of ice and medication saved me from a wrist surgery. I could not
believe a mouse could induce such damage to my hand while using
GIMP.

Hi,
as already replied, all known painting software require the mouse
button to be pressed while painting.
However very few users actually go painting 4-5 hours uninterrupted -
of course, if that is a routine task, the first thing is to get an
appropriate mouse that will be more anatomical. That should minimize
things.
The motive I am writing however is another one: Mr. Noriega, can you
think of a better way of handling painting with the input devices
found in most computers? (i.e. keyboard and mouse - maybe mic).
The GIMP is comunity based, and you can help us build a better
software. Even one that gets ahead the commercial counterparts in
some respects.
There's one relatively simple change I can think of, that could reduce
problems as the one experienced by Hector: instead of requiring the user
to hold the mouse button pushed down during a drawing operation, it's
possible to signal the start and the end of a drawing operation with
separate mouse clicks. I.e. instead of "mouse down -> paint operation ->
mouse up" you could do "mouse click -> paint operation -> mouse click".
