First I'll start off by saying, I'm loving me some MP.

I'm having this issue with controlling the volume via my remote or the keyboard for that matter. Only the default volume settings , Style=classic Control=wave, seems to work with any other combination either not working altogether or just responding to "lower volume" not "Increase Volume".

When playing some music for example, a "Mediaportal - Music/shares" slider appears in the Vista mixer. If this slider is at 100% & I reduce the volume I can't get it to go back to 100% again. It stops at 70% & this happens with both keyboard input or using my remote control.

Any insight would be appreciated.
