"Creating Meshes" in background?

Is it necessary to keep Rhino in focus for render mesh to be created? For instanct, if I do a flow operation on a group of complex objects, can I switch to another application while Rhino does the flow operation and creates new render mesh? It seems I always have to come back to Rhino and waaaaaaaaiiiiiiiiiiiiit…

You should be able to switch to another application while Rhino is calculating anything - render meshes, booleans, whatever - shouldn’t stop the process.
