I consider this my experience of font behavior in WordPad a rather new one: I write some text in WordPad. The default font is Calibri 11pt (oddly enough). I usually prefer Arial so I mark the whole text and change to Arial. Now, when I put the cursor somewhere inside this Arial text again, the font in the font selection box changes back to Calibri (but the size remains correct) and when I write, the newly inserted text is in Calibri, not Arial! You would expect it to be Arial. Even a single character within a word is given the "wrong" font. Like this. Strange, isn't it? Note: it doesn't matter which ever font I choose originally, it has nothing to do with Arial. See attached image for more information (yellow marks text with wrong font) .
