Using high DPI display settings on your screen can result in a change of the layout of BPAD and BPD diagrams, specifically with the appearance of the text size and arrow spacing in these diagrams. To resolve this issue you must change the Windows display settings for your screen.
To do this,
1. Open Windows Settings (click the Windows button on your desktop and type Settings).
2. Select the Display tab and change the setting for Change the size of text, apps and other items to 100%.
Note: In some screens, setting this to 100% may result in the text being too small. In such cases, please ensure you change the settings for the Resolution to a lower value.
3. Log out and log back in the issue should now be resolved.
Note: it is important that you sign out and sign in again for the Windows display setting to be applied.
