All of a sudden, dragging a space in spaces to switch it for another space lags and takes for ever.
Why? any solutions? It didn't happen before.
There are not many apps open, memory's fine, dragging windows in Spaces works great, switching into and out of spaces works fast too.

PS: embedding videos here would be nice wouldn't it?
