Keyboard not working for some users under WIndows

[Robert Osfield]

Hi All,

There is an Issue "Keyboard in osgviewer.exe has no response" that have several users reporting problems.  I have no Windows expertise and no Windows machine in which to attempt to recreate the problem so the only way we'll be able to resolve this one is by others with Windows expertise helping out.

The Issue is:
    https://github.com/openscenegraph/OpenSceneGraph/issues/1064

The bit about EGL looks be a bit of confusion on one of the users part, but this I think it just a distraction from what should be an orthogonal issue.

Have other Window users seen issue with keyboard handling?  Is there some focus issue with Window 10?  Has a Windows update patched how event handling is managed in the Windows 10?  Is there a build issue that can cause such problems?

I'm afraid I have no clue as to the cause, let alone a solution so this post is a call for others to chip in with their own success/failure with recent versions of Windows 10 and the various OSG versions w.r.t event handling.

Thanks,

Robert.
