Doubt about Default Material

[micheus]

MickJ, I'm not sure I can/should fix that.
What I noticed here is that it happens if editing the default material we expand one of those plugins groups (POV-ray, Kerkythea, ...) this information will be stored in the default material for that saved scene (file). When we start Wings again or just create a new scene after that Wings will recreate the default material where those plugins settings are empty.
