As I am hitting the left or right arrow keys to cycle through images using Windows Photo Viewer, the menu bar will inevitably end up stealing the focus from the viewer controls at the bottom. When it does this, pressing the arrow keys does nothing until I hit tab enough times to bring the focus back to the image navigation panel.
Why does it do this? What am I doing wrong?
Please do not recommend alternatives image viewers. That does not solve the actual problem with this particular program.
