When starting the ParticlePanel, I get this error:
_tkinter.TclError: unknown color name “SystemButtonFace”
Any clue, please ?

This color name is unfortunate; it exists only on Windows. Try editing the code to replace this with a more generic color name like “Black” or “Gray”.


Damn, that thing is buggy (lots of tk errors when using menus) but it works better now. Thanks.

PS: well, no, in fact it crashes after a few seconds :confused:
