I've been experiencing a very annoying problem with Word 2010.
I highlight a word (or group of words, or paragraph) to make formatting changes. This includes simply trying to change the text to Bold or Italics.
Instead of changing only the highlighted text, I find that Word changes ALL text in the document. (ie. instead of one word being Bold, all text becomes Bold). To fix the over-zealous text formatting, I then have to click Undo or Alt-Backspace. Then I find that all of the other text reverts back to it's most recent state, except for the text I had highlighted.
This problem occurs whether I use keyboard shortcuts or click the appropriate icons for formatting of text.
Has anyone else experienced this problem? If so, is there a way to fix it?
