Coyote, I've just been testing the latest version on my desktop. The first thing I noticed is that it takes about twice as long to open up, which I guess we can live with.
The bug I've found is when I have an mp3 playing then browse to another song and select it, I get error box...
Run-Time error '364':
Object was unloaded
If I select OK, Mediacar closes but leaves Winamp running and playing the original Mp3. Reopening Mediacar, when I go back into the Mp3 screen, it starts to play the song I had selected previously.
Tried with Gamma on & off
