Mosaick Editing not working

After successfully run all step of the project (Pix 4.5.6; 1140 images, final ortho 3GB stiched properly), just cant edit mosaick. After selecting region - no preview and no action after selecting window. No errors in log output. Project on local hdd; photos on net drive. Try to move photo locally - the same situation. Any clue?

Hi,

It might be related to outdated graphics card drivers.
Do you have NVIDIA? If yes, compare your version to the latest that was published: here.
