I am enjoying Leopard’s Spaces.app quite a bit, especially once I fixed the Finder issue. Most of the time I experience no problems, however, occasionally Spaces starts to misbehave or becomes unresponsive. The most frequent problem I have encountered is that sometimes Spaces will stop switching to the space containing the application I have selected from the Dock. This is very annoying, but fortunately there is a quick fix that doesn’t require you to logout or restart your Mac. Since Spaces is tied in with the Dock we can simply restart the Dock and therefore restart Spaces. To do so open up a terminal (
/Applications/Utilities/Terminal.app) and enter the following command.
This should cause the Dock to quit and relaunch, hopefully fixing your Spaces problem in the process.
