Fading does not work anymore

[corion]

hi everybody,
a little problem with the fading :
when I skip to the next track, the actual continues to play during 6 seconds (the time I choiced in options), and then stop sudently, without fading ; (of course, during this time the next track begins to play (fading into a new tracks : 3s)) ;
I tried tu change options values, without result ...
it's a bug on my new computer ; that worked perfectly on the previous one, and on my PC at work, so it's probably not a MusicBee's problem, but would you have an idea ?

my PC : HP Pavillon Power 580-051nf, Intel core i5, audio NVIDIA

thanks !!
