How can I stop OS X from switching Spaces when the mouse cursor is at the edge of the screen? Mac OS X Spaces change when I hold the mouse at the edge of the screen. Is there an application or 'defaults' command to disable this?

Warp looks like it might help, but hasn't changed the behavior for me, even though I tried turning it off, or setting a modifier key.
I found a solution. The following sets the delay to 1 minute.

defaults write com.apple.dock workspaces-edge-delay -float 60 &amp;&amp; killall Dock
