Volume Control Problems
 

I have noticed a problem too:

If I have both .mp3 and the windows audio files in the same play list, once it plays the windows audio file, the volume decreases and will not go back up on the mp3, even if you max out the winamp volume control. You have to go into the windows xp volume control tool to change it back to 100 percent. any suggestions?
