I use Calendar to keep track of my freelance work. At the end of every day I add a short list of what I did for who. Sometimes a very short list.
Since installing Mountain Lion, I can no longer insert entries into Calendar that have line breaks. Alt-return used to do this, and it still starts a new line while editing an entry, but when you hit return to commit the entry to the calendar, it loses that formatting. So my lists are just unbroken strings of text which are difficult to read and use.
Am I missing something?
