I've noticed it a bit today but not before, I blame the Facebook outage for it.
A down site shouldn't affect an application in this way, but it is still beta and apparently there were some pretty wonky responses coming back. I view it as an opportunity for devs to harden their API code
9.9 seems to work best for me. Have two weird issues with 9.10, like post widget not working at all. Also hitting quit turns on my camera. So i'm stickin to 9.9 and not using 9.10. 1.0 should be here very soon.
