XnView Software

I had to reinstall XnView MP a few months ago and was very happy that the F3 shortcut had started working again on my Windows 10 system, so that it matched my Linux system. Now, a few months later, F3 has stopped working and I am back to having to use alt+1 for opening images in GIMP. Is there a way, short of another reinstall of XnView MP, to get this functionality back? I haven't been able to find anything on it in your documentation or here on the forum. Attached is a screenshot of what my right-click menu looks like.

It's amazing how writing something out helps my brain process things. So, out of curiosity, I removed Gimp from the context menu, relaunched XnView, and F3 now works to launch a selected image. I think this happened when I was trying out a different keyboard and the function keys were messed up so I added Gimp in the Configure programs window. Now that I have undone this, it works as hoped.
