Hello Matt,
Perhaps I didn't explain it very well. Once you have unticked the my workday option, the process is as follows:
1 - Close all windows in Maximizer except for the Address Book
2 - Make sure save settings on exit is ticked
3 - Close and re-open Maximizer
4 - Untick save settings on exit
From then on Maximizer should always open with only the address book open as this was the last saved configuration.
