That make sense in a way, but I thought SCARD_E_INVALID_HANDLE would
apply to errors concering an SCARDHANDLE, not an SCARDCONTEXT? It
doesn't really matter so much, as there really isn't anything much to
do with an error returned from SCardReleaseContext except for maybe
logging it.

Not particularly, just trying to get things as stable as possible. We
have users from Mac OS X 10.2 to 10.5 with all sorts of different
configurations. And quite a few users that seem to like keeping our
application running 24/7 with phases of sleep mode in between.

Regards, Eric
