Hi all,

I am trying to implement the dynamic format changes support in Win7, but I'm facing an issue:

If I change the samplerate by calling GenerateEventList, the format list within the windows control panel is updated. But it happens from time to time (not allways) that the old format that was selected before I changed the samplerate is still available and still selected. If I play a sound, the new samplerate is used though. So it seems to me that this a display bug within the windows control panel.
Any ideas?

thanks,
/Uwe
