Here's another issue...
Because I'm using the default WM6.5 dialer, I now have to use the default WM volume control as well. Otherwise the in-call volume will not work if you use the finger-friendly HTC Volume.
The problem is that in the Settings menu (or any menu other than the home screen), if I use the volume control, it is shifted too far to the right:
Is there a solution for this? Maybe moving the taskbar speaker icon over to the left will help (although I don't know how to do this.. will need to search!)
