-- Bug description --
Random errors when callbacks are called which are set
by uicontrol and which access global variables, e.g.
vvs=uicontrol(vvf,"Position",[40,-16,240,18], "Style",
"slider",...
"Min", 1, "Max", 61, "Value", 1,
"SliderStep", [1,1], "BackgroundColor",BCV, ...
"callback","v_set(vvs)");
====================================^^^
sometimes I get the error message 'vvs not known'
or I get a similar message in a different callback.

-- How to reproduce the bug --
I hope I manage to attach the necessary file.
Unfortunately it's hard to reproduce the error with a tiny
test script.
exec ODE_F_GUI.sce
Mostly, an error occurs before the menu is ready.
If the menu gets built adjust the slider for 'v' to
a non-zero value then press 'Schuss'
The orbit of a football should be shown - it did at least
in Scilab 2.7 (even 3.0 CVS)
