When you see strange things in the camera view, does rebuild 3D fix anything? Sometimes this will fix strange things. If I ever have problems with the "replace" tool, I will go into the dialog and change what I want instead. If you haven't done so already, you should send this into tech support.

I just made the "hole" a normal polyline using a solid fill and the invisible line style. This is what I use pretty much anytime I want to create a mask. This seems to work pretty good unless you need a real hole, like for a counter top or something.

You can click to to place a point light but if you drag you can create a spot light pointing in the direction you want.
