Everything in my simple massing file is fast, except when I move from 3D to 2D window there is a spinning wheel and about 10-seconds lag before I can continue working. I've hidden all layers, deleted hotlinks, tried different things, but it's always 10 seconds. Any ideas appreciated.
Does the same problem occur in other files, or is it only this one project? Could be nice to double-check this, to know if the error is project related or not.
