If you don't like different window sizes in the day, week and month view (BTW where is the year view?), follow these steps:
- Start iCal.app and set the window size of the day view to your favorite size.
- Quit iCal.app.
- Double click on ~/Library/Preferences/com.apple.iCal.plist and the Property List Editor.app opens (the Developer tool must be installed). But of course, you can use any text editor to do this (BBEdit, TextEdit, vi, pico, etc.).
- Now copy the value of the property "1-day view window size" to the values of the properties "7-day view window size" and "monthly view window size".
- Save and quit the Property List Editor.app.
- Start iCAl.app et violĂ : equal window sizes for each view.
You may wish to create a backup copy of your preferences file after editing to make it easy to recreate the identically sized windows in the future.
