Black Bar or Line
A black bar or line across the calendar section of Entry Express (when you are using the PC Desktop version of ChildPlus) is caused by the computer's display settings.
To resolve this:
Right-click on an empty section of your desktop screen and select DISPLAY SETTINGS
in the SCALE AND LAYOUT section, change the size of the text, apps, and other items to something less than 150%.
Once this is done you should no longer see the black bar in the calendar section of Entry Express.
