Apps jumping spaces docs getting caught in limbo?

Is anyone else having issues with applications jumping spaces? I have been assigning apps to desktops using the dock's assign to option. This works, but I notice that sometimes the applications jump desktops without me moving them. I had Lightroom and photoshop in two different desktops but now, somehow, they are in the same desktop.

Also I was opening an attachment from mail in fullscreen mode. It was a word document so it launched word in the first desktop, but after word opened it never showed up in word. When I entered Mission Control to switch to the Mail app, I could see the word document in the preview of the desktop/space of Mail, but when I went to that space, the document was there for a split second, then disappeared. It never showed up in the desktop with word. I relaunched the document, but it did the same thing.

Anyway, just curious if others have seen this issue.
