NetworkManager dispatcher script does not finish when going to sleep

Hi *, starting with the last two NetworkManager versions, my dispatcher script does not finish when going to sleep. It finishes on resume, though, causing some strange effects. It's runtime is 1 or 2 seconds only, so this is not a problem of hitting the dispatcher timeout. Anyway in this case it wouldn't continue after resume, I believe. Any idea, what is happening here, and how to avoid it? TIA. Bye. Michael.
