Thank you. I will follow that advice and if it does not work I'll just keep messing about with the Settings of the game.
Much obliged DjNDB
UPDATE (January 6, 2013): SUCCESS!
The instructions on the link provided above worked perfectly for me and fixed the issue.
Another gamer by the handle iDiPirro
found a way to resolve the issue (almost)*
For those that arrived to this post searching for the same text issue, and have not seen iDiPirro's post yet, here is basically what he did:
1) Go to Settings and turn off
Fullscreen (Shortcut: ⌘F).
2) After you've done that, bring the Resolution to 1280.
3) Then turn off
The text should be perfectly legible from now on.
After you have done all of the above you can then revert all the settings to whatever you prefer, (including maxing all the settings and even turning Anti-aliasing back on, if that is what you like) and it should still work perfectly.
The glitch may return, but if it does just quickly repeat the first 2 steps of the method described above and you're good to go again, at least for the duration of the session you play.
