Hi Justin,

Good! That's what I silently was hoping for;-) - it's a common
occurence that the reason for a SEGFAULT in one piece of code
is actually in some completely different place with no obvious
connection between the two.

I just had a look through the different versions and not allowing
a label within a slider was introduced at least as long ago as the
version 1.0 from Novemver 2002 (no idea when it happened exactly,
that's just the oldest version I still have source code for, ver-
sion control only started in 2003). So it might be considered a
bug in fdesign that it still allows to put the label inside of
the slider.

Worse, that long history makes it problematic to switch back to
the behaviour of the even earlier versions since all code written
since 2002, setting the alignment to e.g. FL_ALIGN_CENTER and
expecting it to be automatically corrected to FL_ALIGN_BOTTOM,
would stop to work properly.

What I could try to do is to add another function to the slider
widget for switching off automatic etting of the alignment to
"outside" if I can find some unused bits I can use for that.
Would that be acceptable?

I've got to put you off on this - I hardly ever looked at the
glcanvas code at all and thus have to figure out what's going
on there myself - I remember having once noticed that mouse
activity seems to increase the rate of redraws but never got
around to invetigate this.
