as i said - forget abt python in the first place. this has nothing to do with your OpenGL troubles. “…is not unknown to me” just means “i’ve seen that”. unfortunately, i can’t remember in which particular situation or how i solved it, and even if it was openGl related. it’s just one of the many cryptic windows (no, other OS’s aint better) error messages i’ve came across.
the driver “solution” i offered may sound complicated, but it’s one way of at least trying to solve your problem. so, don’t hesitate, just do it. for some reason tweaking windows requires quite often messing with settings, removing files, installing and re-installing drivers, hacking the registry or disabling features windows claims to be “…essential for security” or such. BTW, as i say this, it just comes into my mind - disable the system recovery feature. sometimes it prevents proper driver installation (only because windows claims a piece of signed software is the right piece, doesn’t mean it really is. but system recovery sometimes replaces the new files WITHOUT asking you with the old ones).
so: disable SR. download latest drivers. remove Nvidia drivers with the tool (search for that). restart. after reboot, xp will ask you anyway for drivers for a new harware found (yes, your FX5200). install the new drivers. disable anti-aliasing and such… sorry can’t tell you more, i stopped using windows 3 months ago - i don’t miss anything, and memories vanish quite fast.
