I installed Windows XP tonight, I had been using Windows 7. I have a Microsoft Natural Ergonomic Keyboard 4000 with Back/Forward buttons that can be programmed to be next/previous track. They work fine with Windows Media Player, but I like Winamp better, though I'm having an odd issue. The button works for next track, but will not work again until the song is exactly 10 seconds into it. Pushing the button does nothing, but once 10 seconds has passed I can skip to the next track. This is pretty annoying and I figure has something to do with Winamp settings considering the buttons work fine for other media players. Does anyone know what the issue might be?
