greyed out options?

[Robster]

I have used a previous version of hoster 3. something but i have just bought a new laptop and bought hoster 4.03

my laptop is a fujitsu siemens amilio Li 2735 it has a dual core 2GHz processor 3 Gig of ram

everything works fine BUT the x-fade button is greyed out and not pressable
the audio controls button is the same in the tools options and the play full song option is not selectable either

The program works flawlessly apart from this

any advice ?

is it the built in realtek hd audio manager thats at fault?
realtek info says its
audio driver 6.0. 1.5549
directx 10.0
codec alc268

any help and advise is very gratefully recieved

many thanks

Rob
