When selecting multiple files in the Xnview browser the state (enabled/disabled) of the menu items "Open" and "Fullscreen" depends on the order of the multi-selection.
Effect: Irritating user-interface; expected functionality not available
To reproduce:
0. In XnView browser browse a folder with image files (e.g. JPEG files) and non-image files (e.g. DLL files from XnView MP installation).
A1. Select a non-image file
A2. Enhance your selection by pressing Ctrl key and clicking on an image file
A3. Right-click on the image file to open the context menu.
Actual behaviour: menu items "Open" and "Fullscreen" are enabled.
A4. Close the context menu by pressing "Esc" key.
A5. Right-click on the non-image file to open the context menu.
Actual behaviour: menu items "Open" and "Fullscreen" are enabled.
A6. Close the context menu by pressing "Esc" key.
A7. Deselect all files
____
B1. Select an image file
B2. A2. Enhance your selection by pressing Ctrl key and clicking on a non-image file

Actual behaviour: menu items "Open" and "Fullscreen" are disabled.

Summary of actual behaviour (bug): State of the menu items "Open" and Fullscreen" in context menu depends on the order of your multi-selection. It does not depend on the contents of your multi-selection or on the image that you perform the right-click on.
Expected behaviour: Context menu must not depend on the order of your multi-selection.
