The Fog of War selection button on the GM Toolbar is acting like the Layer selection - Click, then click which sub-category (Layer vs Reveal). It should act more like the Drawing Tool button - Click - auto-select previous sub-category, override if another sub-category selected. I've heard way too many GMs complaining about the Fog of War button not working, and there's no reason not to default to the Fog sub-category that is displayed on the button. Solution: One click on the Fog of War button should select it, with the last sub-category (reveal, hide, polygon) used.
