CLS DC-10 Tooltips

Crew Dogs,
In the DC-10 from CLS (I fly the KC-10 "Extender") the cockpit tooltips appear as black blocks on a white background instead of words as I pass the cursor over the functional switches, levers, buttons and gauges.

Does anyone else have this annoying problem?
Have I done something wrong (installation/configuration)?
More importantly, does anyone have a fix?!!

The aircraft is great; easy to fly and just as unforgiving as the real machine in certain instances - "... never get behind the airspeed/altitude on final. The engines take ther own sweet time spooling up."

Thanks!
