Quite more investigations at my side, but no easy solution.

Poser on Mac seems to use TCL and TK frameworks/libraries for running python compiled code. On OSX 10.5 there is version 8.4.7 while OSX 10.6 uses 8.5 and 8.4.19 for backward compatibility.

During my tests I replaced whole 10.6's TCL/TK frameworks with these from 10.5 and pose2lux start to act just as under 10.5 (with some menu glitches, but without corrupting Poser). Other method that I used was just replace under 10.6 folders for 8.4 TCL/TK framework/library which is bit safer.

If someone is interested to play with these files, they are located in /System/Library/Frameworks/Tcl.framework/ and /System/Library/Frameworks/Tk.framework/ To make changes in these folders you have to have root privileges.
