Terrain Brush Bug

Hey guys,

So I've playing around with Unity, but I've noticed that there's a really annoying bug with my terrain brush. It basically doesn't recognize or save any changes to the brush and the only work around to save the changes are; to perform the changes, select an other object and then go back to the brush. Big issue with this work around is that I can only choose one texture since it will always reset to the first texture.

It's a shame because I'm really happy with my current scene, so any solutions would be welcome!

EDIT: I Googled and found several other posts regarding this issue, but none of the solutions was working so far.
