Dashboard developer mode problem
I've used Dashboard developer mode (enabled with a defaults Terminal command "defaults write com.apple.dashboard devmode YES", or with customization provided by such apps as TinkerTool) since I upgraded to Tiger to allow me to activate Dashboard, grab a single widget with the mouse, and, while the widget's icon is still in the drag state, deactivate the rest of the dashboard widgets to leave active only the one I grabbed. Using this method in Mountain Lion, the widget disappears when I follow the procedure, and the only way to get it back is to bounce Dashboard (turn it off and back on again) using a method such as executing these two Terminal commands, killing the Dock after executing each:
defaults write com.apple.dashboard mcx-disabled -boolean YES
defaults write com.apple.dashboard mcx-disabled -boolean NO
Is there anything that causes the disappearance of the widget that I can change or remove? Toggling Dashboard every time I want to make a single widget available for use is very inconvenient.
