Okay, so if I use the native OS X 10.11.2 driver for Nvidia everything works. If I load the Nvidia web driver I lose sight of the Simulator settings and the Navigator. The action is still there if I move the mouse in the area, but I can't see the icons. This started happening with one of the Nvidia web updates while I was running Yosemite and has carried on for the last four or five updates to the Nvidia web driver. Anyone else using OS X 10.11.2 (El Capitan) with the latest Nvidia Web Driver?
