Did that. No Joy.
I am getting the following in the log as I am debugging:
CmdGetRemoteRtnName error: ILLEGAL ADDRESS
CmdGetRemoteRtnName error: ILLEGAL ADDRESS

} while (event.eType != appStopEvent);
The point where it crashes is very consistant.
I've been beating myself up for three weeks on this bloddy error. Tried all
sorts of things. Anyone up for a little consulting? (cash)
Thanks,
Jim
