"save envmap" = "Sorry, not implemented yet"???

Apparently I am missing something painfully obvious… :eek: I followed all the directions for environmental maps (using http://en.wikibooks.org/wiki/Blender_3D:_Noob_to_Pro/Build_a_skybox as a guide) but when I select the “Save EnvMap” button - all I get is a text-over saying “Sorry, not implemented yet”. I’ve read a couple other tutorials and searched these forums without finding any key element I’m missing.
I have the material ‘map input’ tab set to REFL and ‘map to’ set at COL… I could upload the blend. if necessary…
Thanks in advance.

What version of Blender are using?

Sorry - (DUH!)
I have version 2.45 installed…

All I can say is it works in 2.44. Sorry haven’t downloaded 2.45 yet.
