If you have Windows 7, you can (through its personalization feature (right click on a blank spot on your desktop to get started: the discussion is in the thread) change the size of "Menu" in windows. Also, if you adjust "Message Box," you can make the font bigger on your Opera tabs, and alongside your personal tool bar folders. I changed mine from a font size of 9 to one of 10, and the change is relatively modest. I tried 11, and it was greater. I tried a bold, and it was very pronounced. So I went back to 10, non-bold for the time being, for a modest change. I don't think the choice has to be too small or too large (which is what you were concerned about in your post). Now when you make a change to Menus and or "Message Box," in Pesonalization/Windows, it applies across the board in Windows, so it affects your font in your right click context menu, and menus and some other items elsewhere, but if you need the change in Opera, it may be fine elsewhere for you. You can also in Personalization change the display for the overall font, or rely on the zoom feature in the Opera menu for that. Just remember what you started with on your settings, because you can always return to it.
