For those of you running WM6.5.x, you will have noticed that the volume on-screen slider is not the the standard HTC one. Turns out, Microsoft has been playing with the volume hooks and HTC's skin is no longer compatible.
Instead, we're left with the functional but ugggggly old-school windows volume rockers.
One solution is from XDA member Ponchofiesta (love it) who has a new app that improves the graphics tremendously. The app is still in early beta, so expect some bugs and you need to have .NET CF 3.5 installed. Make sure you lend a hand with feedback.
Still, once stable enough, this is something ROM chefs can cook right in and make it all bettah.
Alternate solution? SetVolume 0.7.
