Hello everyone, I need to start my first post here with problem.

I am not sure what I done, but when I was evaluating trial i must did something and my properties window keep disappearing when I set some value or do something in that window. And it happens like 80-90% of the time. If that happens I need to select some thing (body/fixture/whatever) few times to it show again. It must be something in settings, because even in full version this thing is still happening. But I went through options I can`t find anything relevant.
Is anyone had this thing going? Can someone help me?

Thanks for the report!
What operating system and version is this occurring with?
When you say the properties window is disappearing, you mean that the contents shown in the properties panel is disappearing right? Not the whole window? Is it the same as shown in this video? http://youtu.be/LIsqrV6geNo

Windows 7 x64, rube-win32-1.6.0.

Yes, exactly the same problem.
