Hi
I just experienced this issue , where i have a see-through frame buffer, Easily resolved by clicking the corner and resizing the window.
I was also wondering if there is any way of reopening the frame buffer while render is still processing other than opening up the render setup, could a Show VBF be added to the main toolbar? Or is there a toolbar i haven't opened?
Thanks
Fallen
Edit: Please be aware my render time was just because i left it on overnight :)
