I installed Win7 a couple of weeks ago and had no problems getting NHancer to run in FS9 - using the recommended settings, I had good AA etc in both windowed and full screen modes.However, 2 days ago, when I changed to full screen, I had a completely distorted picture - it appeared that the picture was too big for the screen {C172 2D panel I could only see the coaming and above} and the picture seemed at extremely low resolution. The same applies in spot and VC etc. I tried several different NVidia drivers, re-installing NHancer and FS9 and even re-installing Win7. The problem remained - good AA etc in window mode - v distorted picture in full screen.Also, using the NVidia control panel to set the AA without NHancer I had no problems. I also have FSX installed and have no problems with NHancer in full screen.V grateful fo any ideas as to where t I might try next.John R

When you are in the 3D mode try going through the Menu and reset the display options.
