Device notify plugin not working 100%?

[Xantho]

I have some problems with the Device Notifier Plugin:
I'm setting one Multi-Group with an OSD Popup for each Event (Arrive + Remove)
Only to test if its working ok.

But only the last Multi-Group I add responses to BOTH events.
Also If I change the CD in my second CD-Rom: The same Multi-Group is starting.

Any Ideas?
The Event Logger says correct
Drive Y arrive, or Drive Y remove or
Drive Z arrive / Drive Z remove
(Y is my CD-Rom, Z my Burner both SCSI)
That means different Events, but the
same Action?

Please help me

TIA
