I have this crush always when try to rotate the 3D contour plot in its figure
window.

The issue occurs only *if the contour labels are shown* by setting the
ShowText property to 'on'.

An example of script causing this crash:

b1_vect=2:0.1:5;
b2_vect=2:0.1:5;
[B1, B2]=meshgrid(b1_vect,b2_vect);
sigma=B1.*exp(-B2)
contour3(B1, B2, sigma, 40, 'ShowText', 'on');


When contour3() is used without the option 'ShowText', there is no problem,
graph can be rotated in its window. E.g. the line

contour3(B1, B2, sigma, 40, 'ShowText', 'on');

works well. Therefore, if the 3D contour plot is drawn this way, one can
rotate it.
