Landing lights interfere with advdisp.dll?

Hi, folks-I think that by any reasonable measurement, the 738-9 is the most outstanding complex commercial airliner that has ever been created for Flight Simulator. Being able to fly almost entirely in VC has revolutionized my flight experience!I have run into one problem. I use advdisp.dll with Radar Contact to display messages on a second monitor. Both monitors are driven by a Ti5900 w/ 128 MB of VRAM. I find that when I turn the landing lights on (in VC or 2d panel) advdisp stops displaying any text, or the text flickers considerably. When I turn the landing lights off, text is displayed normally. This doesn't happen with any other lighting system and didn't happen with the 700.I've made sure that my hardware lights are set to 8 in my display properties, and deleted and recreated FS9.cfg. I haven't made any updates to my display drivers- I was using the most recent NVidia drivers with the 700 and am using the same after upgrading to the 800.Is anyone else having the same problem or does anyone have any ideas how to solve this?-Simon Binder
