I did defrag the PC and that helped a little. I also deleted quite a few flt sim files from the Recycle Bin and that helped a little. Then I turned to the "help" button in flight sim X and it gave me a place called "out-of-memory". Well, I'm laughing out loud at myself because here it says, "Run Disk Cleanup", then says go to "Start Menu" then, Programs, then Accessories, then Syst. Tools, then "DISK Cleanup". What's funny is, I don't know if they are talking about pressing the "start Menu" of the PC or the Flt Sim Program. So, I haven't been that route yet. Whew, I'm out of breath. So far, I appreciate your thoughts and suggestions. I'm not real PC smart, so I'll have to go slow but I think I'll get there. Thanks to everyone. Gipper
