That's good news! Thank you! It seems that several new files, which are included in the bz2 distribution, are missing in svn trunk. For example create_shadertext.py, modules\pymol\constants_palette.py and some files in data\shaders. http://pymol.svn.sourceforge.net/viewvc/pymol/trunk/pymol/ Christoph ------------------------------------------------------------------------------ Try before you buy = See our experts in action!
