I'm not sure how it is when wake-from-suspend freezes the applications, but it can't really be a system problem (like ping, which would be unrelated to the session). After all, restarting X (ctrl-alt-bs) and logging in again works just fine, and all apps work again.
During normal system operation, of course.
