Volume control in visible player flashes on then off and stays off

[Jim Schaubeck]

I'm writing a Music on Hold server with players.  On the visible players,
I'm not able to use the sound adjustment on the left side (in IDE mode).
The volume bar shows for a split second but disappears.  Oddly, if you click
and hold, you can actually adjust the volume but you can't see what you are
adjusting it to.  Using a button to set the filename of the player with a
.wav file.  Everything works fine but the volume control.  I'm using XP pro
with rel 2.9.

 

Has anyone else seen this?

 

Jim.
