Posting another one. It's not must have to be fixed, just for better look.
I using high DPI display, so on default settings, fonts and other UI elements are too small for my eyes.
So I changed DPI via Windows settings to 200%.
I'm using Windows 7 SP1. After 7-ZIP 9.33 installed and context menu icon display enabled,
context menu icons are too small... for 7-ZIP.
I have some free software, like TortoiseSVN, Notepad++, which have no this problem.
