If you have v 9.1.8 you have the latest (same) version as the AppStore one.
Logic defaults to using MIDI CC7 to control the channel strip volume ( and a few other CC's as well), and there is no quick/easy way to stop it. Whilst updating to OSX 10.8.4 might help with some other issues, it will not help with this particular one
Best solution would be to use some other CC's that Logic does not directly respond to, such as the ones you mention.

Thanksyou CCTM, I only mentioned the OSX vesion because some replies would be that I wasn't even up to date as far as the operating system was concerned. I will just give it a try and for taking the trouble to help with a somewhat coy anser you have helped,thanks again.
