If I start Blender and, with the default scene left untouched, click on the material tab, followed by the texture tab, then I see a defined texture. However, if I then click on the particle system tab, followed by the texture tab, I don’t see any defined textures. This is reproducible. I can click around among the tabs, while the texture plays hide-and-seek depending upon which tab I viewed previously.
What’s up with that? Does anyone else see this behavior? I’m running 2.64.
