Disappearing Geometry

After working in Max for a while suddenly all objects disappear from the viewports exept for Max gizmos (lights, cameras etc). Everything is there on render. Max needs to be closed and reopened for things to reappear.
Anyone experience this?

Thanks!!!

sounds like video card issue. I.e. memory buffer gets clogged up and then does not clear up. Try perhaps different modes for view port, i.e. direct x or open gl see if that helps.

Thanks! I’ll try that.
