I'm trying to display map more or less like described here: http://pymolwiki.org/index.php/Display_CCP4_Maps
It works fine for isomesh, but if I change isomesh to isosurface (which takes the same arguments) only the part that is inside unit cell is shown.
Since there is a note in the changelog "* isosurface and isomesh now use the same ranging criteria",I think it's a bug.
I see that there are some differences in layer3 between ExecutiveIsosurfaceEtc() and ExecutiveIsomeshEtc() (the former is always calling Object*FromBox() and the latter is calling Object*FromXtalSym() if there is symmetry in sele_obj), but I haven't looked into details.
Here is a picture:

The surfaces are created like this:
load thaumatin_out.pdb, pdb
load th11.ccp4, map11
isosurface s11, map11, 3.0, pdb, carve=5
isomesh m11, map11, 3.0, pdb, carve=5
