I'm having a problem in 114 that I didn't see in earlier versions. I'm playing via a library server (currently running 113).
The problem first manifests itself as the mini window disappearing. I don't notice exaactly when this happens, but it is gone. The icon is still shown in the toolbar, and it is still active (i.e., I can pause, etc), but even if I click on Show Media Center it isn't shown.
Once this first problem occurs, then another problem also happen. Every time a track is done playing I get an error window popping up. This window says:
Error
JScript Error.
Code = 800x138f
Code meaning = Unknown error 0x800A38F
Source = Microsoft JScript runtime error
Description = 'undefined' is null or not an object
This error pops up many time simultaneously, roughly 10 time. I can click Ok on each one and the finally go away, but as soon as the next track is completed then they pop up again.
One other problem I'm seeing in 114, which probably unrelated, is that when connecting to my Library Server, MC no longer remember my username and password when I first start it up. I only have to enter it once every time I run MC, but it used to cache this info.
