Just got ActiveSky and installed it. The manual says the flickering screen is a known issue, that happens on some older systems, and to uncheck "Render to Textures" in FS Display settings to solve it.Two things, tho: First of all, my system is not that old, and my graphics card is six months old. My 2MHz system seems to be well beyond what they recommend as the min. (I know they aim low, but still, 800MHz vs. 2GHz...)Second, if I uncheck the "Render to Textures" box, I cannot load up my game. It crashes every time.Anyone else have a solution? Would appreciate any feedback.John

Hi John!Have you downloaded any special cloud texture sets like the FSW ones? If so you have to use the 32bit clouds and not the DXT3 if you want to disable "render to texture".JT
