I might give that a try, thanks.

There is no update for the original driver so it looks like the detailed diagnostics is the next step. Thanks for your suggestions.

The driver used when the card was changed came on the installation DVD which is probably an old driver, maybe a driver update might sort the problem ?

I have re-installed X-Plane 10.36, re-installed the Saab 340 and it still does not work - no Gizmo toolbar, unable to make any selections - used up the last of my 3 installation downloads. Is there any known conflicts with graphics cards as it worked perfectly until i replaced my original card an AMD Radeon HD6450 with an AMD Radeon HD6670. Help !!

Yes I have, it still doesn't work, maybe the graphics card upgrade has corrupted something within X-Plane. If all else fails I will re-install X-Plane and start from scratch.

Aircraft installed and operated well initially but after upgrade of video card no gizmo toolbar visible and aircraft loads with all doors and hatches open. Aircraft re-installed without success, all other aircraft in X-Plane work fine, it appears to be a Gizmo plugin problem - any ideas?? Log.txtgizmo_prefs.txt
