Hi Folks, I am an almost 73 year old flight simmer, who needs some HELP. I am have been using FS9 for many years. In fact I started simming with PRO PILOT '99. I have never had this problem before. When I am flying, I get Bloches of various color in the scenery, which comes and goes. Sometime these colors are in a pattern, dashes or dots, (yellow, red, green, orange, blue), they are four to six colums wide and eight rows high. In the cockpit I get regular patterns of these dots on the screen. I have uninstalled and installed FS9 twice, to no avale. I have run several tests on my graphic card and this passed. I love to sim, but this driving me crazyyy. Any help would be appreciated.
