Another Spaces Bug - Searched Couldnt Find Help

So ive been having an extremely annoying buy in spaces on my macbook pro (15in c2d 2.33 2gb). About a month ago for some reason my up-down-right keys stopped working, not water spill they just kind of stopped. Im going to get it fixed by apple care soon, but anyways because of this keyboard failure ive been forced to navigate around my spaces only using command-left. Well ill switch pretty quickly between all my spaces, and sometimes its fine, and then other times the apps just go away. They dont crash, they are still active (cause i can still save word files, just cant see the dialog, thank god). Anyone heard of any fixes for this? Anyone else having this issue?

P.S. when i mean active, i mean they dont show up on the desktop, if you click their icon they wont show up (so its not like theyre hiding), and the only way to get the application back is to quit it and restart it.
