sometimes, running a sound app in Squeak (such as in "Fun with Music")
seems to lock up the sound driver so that sounds cannot be used from
elsewhere in windows, or even from Squeak itself. - logging out and on
again is not enough; I have
to reboot.

Is this a known problem with a known solution? e.g. restarting an NT
service ?

(this is a repost - the first one seems to have got lost)
