I would like to ask why, in the event window to create or change the dates you can not enter but you must enter or correct through the calendar that appears. If you are short intervals of time the operation is fast, but if you are far away (like 1974) it takes a long time to do it. There is another method faster?
Don't click the drop-down button, but click where the year-position.
When the year-position is highlight, you can direct input year-number, or use up/down keyboard to adjust.
