This is the best fix so far :
You fix this if you right click on the left most are of WMP main area, and tick/check "Always show Now Playing on top". This DOES fix the problem, but this also makes WMP permanently sit on top of all other windows. I dont like that. If I click on Explorer
below WMP, then that mean I frikkin want Explorer to come up over WMP. I dont know why MS added this. BUT.... by adjusting the WMP screen size, I can get it to be less annoying. But most importatly, the issue that this thread is about can be fixed. Now
when you play videos, the list pane does return for music (most of the time ! occassionaly it still dissappears)
WMP12 is almost perfect. It lacks support for FLVs and MKVs, but it`s biggest problem is that you can NOT pin the "show list" pane.
ARrgggggghhh!!!!!! %$^# Microsoft. When you do schitt things like this, you deserve to have Apple get the success it has. You have the world at your feet, and you keep shooting those feet.
