Can't get Compiz Negative effect working

[tr333]

I was using Super+M keyboard shortcut yesterday to enable/disable the Compiz Negative theme (inverted colours), but now when I do the same keyboard shortcut it just opens the Mail/Chat/Broadcast menu next to the date/calendar/clock in the top panel. Any ideas/suggestions on what I might have done to change this?

Apparently, sometimes it works, sometimes not. Please see my earlier post regarding this:

- When I tried those feature once before, it worked.
- Then, upon writing the mentioned post, it didn't.
- And now it works again. :P

Greetings.
