Additions in version 4.6:
Further dust removal...
Mouse wheel support was programmed but inactive. Was it ever active before? It is not clear.
Anyway, now, it works - on Windows 10 and probably other Windows versions.
Like in every other app, the mouse wheel movements translate into vertical page scroll movements, and Ctrl Key + mouse wheel do zoom in / out as expected.
Just removing some dust on this project...
The latest change is purely cosmetic, but useful: buttons are better visible in today's very-hi-res screens.
