Went to a customer's place today to do some cabling and they asked me if I could make some changes to their Call Pilot (change class of service to make no expirey on passcode). When I was hooking up my laptop, I noticed that they have a ver. 3 CP100 running on a CICS ver. 2 expanded.

I know from the compatibility charts that this isn't supposed to work (minimum CICS ver. 4.1 for CP). It appears to be working though. Anyone ever have any issues with this?
