I have one thing that niggles me about carrara, every time I open a new scene the screen is black until I click on it.
I set the scene up, but find  using the manipulator also doesnot change when I select from the sidebar (IE if I had movement manip the change to resize, this does not come into effct until I click in the work area which can be annoying sometimes)
I then do a render and when I return to the assembly room the screen is once more black and I have to click in the screen again.
I just want to know if its me or if this happens to others and it is normal?
