I think I might have mentioned this a while back and was hoping it would be fixed in the RC but alas, no. I've scoured the internet for a fix and a few people have mentioned it as a problem but I can't see a fix for it. Prolly a registry tweak or something:
When playing an MP3 with WMP12, because of the new taskbar, playing a song causes the WMP window to maximise. This also makes it the active window, meaning you have to click explorer again to make that the active window. If you then play another MP3, it maximises WMP again, and makes it the active window. Very annoying if you flick through a large number of song files. I realise I could install winamp or use itunes, but I like wmp and would prefer to keep using that. In previous versions of windows/wmp, the mini player meant wmp stayed minimized when you opened a new song.
Has anybody been able to get around this?
