Stereo Tool

Hello,
We have a system over here with Proppfrexx (in test) & Stereotool 7.60 VST plugin including FM.
In stereotool vst , we use the 'fm soundcard' option, selecting the correct card.
But we noticed that if we restart proppfrexx, the 'fm soundcard' always returns to the default microsoft 'card' (microsoft geluidstoewijzing).
Even after we save every setting, the fm output always goes back to the microsoft card. (all other settings are saved correctly).
Is this a bug in Steretool VST 7.60? (or within proppfrexx?)
Or am I doing something stupid.

cheers
