Have just installed the Leonardo MADDOG PRO and I experience the problem with flickering switches. I have been at http://www.flythemaddog.com/support.phpand followed there suggestion to install the flickering fix file. In my case it does not help. I only have this problem in FS9 (not FSX) and in full screen mode.I have posted in the madddog support forum but see no reply there so I would like to ask here if anyone else is unable to fix this problem? I use Win 7 Home Prem x64 english version.

Perhaps it is because you're using the 64 bit version. They failed to mention this particular registry entry is useless on 64 bit Os's. I had to add the following to the registry key:The original- [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Direct3D]"DisableThreadedDDI"=dword:00000001The one for our 64 bit- [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Direct3D]"DisableThreadedDDI"=dword:00000001:( And restart after the add.
