I have a repeatable (for me) bug in L4Mac 4.5a (4.51.0.2048) on a 27" iMac. I create a new prayer item, put in the title and details. then when I go to change the date and set to weekly and pick a day, if I click above the new item (white space anywhere) the entire Logos window disappears. The program does not crash, because the floating window on my second monitor stays there, and if I [cmd]+[tab] to a different application and back the window reappears. However at that point I am stuck with a floating popup with the day of the week that cannot be dismissed, acted upon, or in anyway gotten rid of except for closing the program.
here is a cropped screenshot.
