Hi guys,
I occasionally have an extremely irritating problem, my dog likes to pee on a specific part of the garden and it's killed a perfectly circular patch of grass. JK.
Also I have another problem. Sometimes when I've set up background bitmaps in Rhino, one or two seem to disapear when I hide a layer or object. It makes no sense at all, why would a bitmap be dependent on the visibility of a layer or object? Has anyone else encountered this? Any way to fix it? Thanks

.
Will.
