>This is a SWAG, but maybe you could experiment with DOEVENTS, since you're working with Outlook and not just VFP.

I did get this working. I did the following:

...

loSysTray = createobject("mySysTray")
loSysTray.Tag = "Run"

do while loSysTray.Tag == "Run"
   read events
enddo

...

* Proc Of Class Definition for mySysTray
   PROCEDURE icondblclickevent
      this.RemoveIconFromSysTray
      this.Tag = "End"
      CLEAR EVENTS 
   ENDPROC 

It works but I'm still not sure why the read events doesn't continue to read the systray events. According to Fox Help, read events is supposed to read events until a clear events is issued. My code never issued the clear events. So the mystery remains but the program works.

BTW, I wasn't quite sure where I'd use the DoEvents ... had the above not worked, I would've at least started toying with that thought. <g>
