How strange. Probably unrelated, but I was getting a similar problem in VMWare Workstation 8, however this was after I had uninstalled Start8 (this was before the new beta came out with the Win7 style start menu). An upgrade to Workstation 9 fixed it though!

I got this to happen by accident, although now I cannot reproduce it! Through some sequence of trying out all of the options I got the hot corner working as you describe, but then after a reboot it was back to normal!
