Right Button in GAMBIT
 

I am trying to use GAMBIT on a RED-HAT server. The Right Mouse Button cannot open hidden menus. Any experience what needs setting? All other Buttons seem OK. The set up works well in FLUENT.

I found this trick by trial and error:

Press down and hold left mouse button on the menu button,
Now while keeping left button pressed down press down AND hold the right mouse button and you will see the hidden menu,
Keep down both mouse buttons and move the courser on the symbol of the command you need,
Now release both buttons at the same time and its chosen.

Unfortunately, I have not found any way to rescue gambit when it's stock by just right clicking on a menu button so I have to kill the process every time I forget the above procedure! Does anybody have a clue?
