Missing Pixel information window vray 3.00.03 - max2011 x64

As the title says, how could i show it?, even if i press the button on VFB it doesnt show, normally i just rigth click on the pixel i want info. It occurs from time to time and its not scene dependent.
Thanks

Is it possible that you moved it to a second monitor or something like that?

Best regards,

I have two monitors on my main pc and i have worked on that scene and rendered too, but my colleage rendered that scene on his pc with only one monitor, so is possible. But ,Is there a script command to bring it back to its original position on the screen or a fixed place?, i have one to put the isolate window when it disappear. So i thought maybe you can provide something like that.

You can try :

*) Save V-Ray settings - System / presets
*) reset V-ray - Assign 3ds max Default scanline engine click OK, then reassign the V-ray one.
*) Load the previously created preset file.
