GVP, I'm not getting any prompt to load disk 3 (the message menue disk) in the 2.4 PPak update. Should I be getting a message prompting me to load Disk #3? Is this message menue disk the same as the origional (2.0) if indeed it is the same, perhaps there is no need to install it in my system. However if there are new additions to the message base then i'll need to load it right! Thank's Bruce
