Hi list: Arlene here! I noticed this with my first xp box. If yu use your disk drive or listen to music switching from disks. What I noticed was this. When using winamp If I had switched to various disks. Then later I try to play a song on the hard drive. What winamp did was this. I'd go to the player itself. I'd see that I had been playing for instance, my Beattle's disk. I could not play anything because the computer was locked on to the last thing I had played. So I had to get the beattle's disk. When I turned off the player. Waited a few seconds. Then Winamp let me play other stuff. Not with windows 7. I have an acer desktop It did the same thing as my old Compaq did! But the old xp box was forgiving. When I went back to the disk it thought I was playing. I did the same as I did with my old computer. But when I went to play something on the computer This windows 7 still acted like I was playing that beattle's disk. I went to it 3 times and it still locked on to the Beattles. So I did a restart. Then when I was back up and running. I went to my music and played something that was on the computer. It went to work as though I was not playing the Beattles. Why is this so? Do you think this is a windows thing? Sometimes with this Acer I can get away with not having to restart. I hope I made sence!
