Hi,
It is possible to recompile Vizard and all of its plugins to link against python 2.4. However, I'm not in the position to make this sort of decision. You would have to take this up with
support@worldviz.com.
You can already run Vizard without opening the GUI. It is possible to use other Python editors to program Vizard scripts, but the main Vizard module still uses Python 2.3, so it wouldn't make any difference.
