New function for FinchToolImpl to use for managing selections in conversation log.

changes to: GetCurrentConvID

Swinehart, February 2, 1986 11:01:59 pm PST

intID.stateID couldn't be maintained properly. Change intID.reqID to be a semi-unique value (cycles every 2^16 requests), and look for that only in incoming reports. They'll have (correct) stateID values in them, too, but we don't use them for anything. Fixes a problem where some requests were being played multiple times, others not at all, if things were queued.
