Fonts are totally useless and misbehave

Edit Subject

The fonts are almost impossible to work with. Have instances of a bigger font reported as a small point size than a smaller font. Highlighting all and changing font size doesn't work. Some parts of a highlighted sentance will change or won't at all.
The list is endless, in fact the problems with writing emails is so bad I have now gone back to Outlook; I can't be beta testing an alpha product anymore.
