I also have occasional freezing of AC during opening or running interface.
My biggest trouble is no autosave function of progress note. If anything happen during writing note before forwarding the note, it is lost. I wish we have certain autosave function which is PRACTICALLY helpful(instead of unstable saved file - which disappears when I attempt to open new note).
I experience frequent problems including loss of forwarded chart. But I figured out those were from the malfunction of my wireless router. Router seems like unstable(because of windows vista?) and forwarded chart is not delivered immediately which makes me shocked. Anyway these were the problem of my router.
Good luck.
