Kmix launching in full size at KDE startup

[Dripple]

Hi all,

I'm a happy Kubuntu user since 5.04. I recently updated my box to KDE 
3.4.1 and installed ThinkPad Buttons, for I run Kubuntu on a Thinkpad 
T30. I don't know which one did this, but now, at each KDE startup, KMix 
is launched in a full window instead of minimized in tray.

Anyone knows how to prevent this ?

Thanks a lot.
