Using XnView MP 1.5.0 on iMac with Intel processor.
When you open more than one image in the viewer and then switch between tabs, the file name (or other information) in the title bar of the program window will not be updated accordingly.
I consider this a bug. If it is not, then please move this topic to Suggestions.
