Spaces is being weird. Help!

[catjacket]

When I try to move applications and spaces, it goes haywire. As in, I'm working on Word and move spaces to Google chrome. But then spaces goes crazy and automatically starts flicking between the spaces, sometimes pausing for a little and then moving again. Whenever I try to select a window or control spaces, it freaks out more until I eventually get it to calm down.
Any ideas what I could do about it?

It would help to know what OS version, computer type, and mouse (if any) you're using. Also if you've installed any 3rd party modifications/add-ons/utilities that might affect Spaces.

Possible causes are trackpad weirdness or mouse driver settings, but that of course depends on what you've got. And there were major modifications in behavior between Snow Leopard and Lion. Could also be that you've got a hot corner set and it's acting up.
