Hi, i dont know if there is a easy sollution for this but i'm used to open a song or a list of songs,
and then, open another different song from windows.
With another players what it happens is that it cleans automatically the list of songs and start playing what you has just opened,
but in musicbee what happens is that it shows a popup saying :
"another instance of musicbee is still running and need to be terminated from the windows task manager."
Is a little pain to have to erase the list of music and then drop the file i want to play or close
and reopen the musicbee when you can just do that by a simple "enter" or "double click" into the mp3 file from windows.
I think an easy sollution would be to, when opening an mp3 file with musicbee from windows,
it opens it and kill another instances of musicbee, that's all.
