Desk lamps stuck at full

Hi Folks,

Another weird one.  We were doing a show on NYE, and the desk lamps were on at full.  When I tried to change the level through the browser, there wasn't any change.  I could adjust the monitor brightness.  I thought that someone had messed with the analog dimmer on the back of the Cobalt 20, but it didn't have any effect either.  At intermission, I played with the dimmer to no effect.  When I unplugged one of the desk lamps and plugged it back in, it responded to control.  I then unplugged and replugged the other desk lamp to get control of both desk lamps.  After that the lamps were under the software and/or dimmer control.

I had just two days before upgraded to the 7.3.1 build 40 from build 39.  I was working with the house lights on, so I might not have noticed if the desk lamps were bright.

Take care,

John
