How to disable moving between workspaces feature?

view story

http://unix.stackexchange.com – I have installed Linux Mint 14 Cinnamon - have been upgraded from Linux Mint 13. There is a feature: i can move between workspaces by moving cursor to the edge of screen and holding it there for about 1.5 seconds. It is very useful, but sometimes annoying. And i cannot find where to turn off it. I would appreciate your help, thanx. (HowTos)
