If I start a new document and the first thing I do is insert the current date/time from the edit menu, the font used is Helvetica, even though Courier is the default font set in preferences. Helvetica stays set for all subsequent typing. If I type a word or two before inserting the date, the inserted date will be in Courier. I have tried this in two project and am seeing the same behavior in both of them. I don’t use Helvetica in any of the font settings in the program preferences.
Another, minor thing: the date format is year, month, day. As far as I can tell, my system is set up for month/day/year. Is there a choice of formats?
