Click the right button on a book and check/uncheck Compare mode
Toolbar Icons:
This powerful command allows you to compare several Bible versions in a single
window. In this mode only one verse from all the visible book windows is displayed.
If all the versions to compare do not fit in the window, a secondary scroll is automatically displayed.
Any of the book windows can be switched to compare mode.
Information for advanced users:
The issue with character pages of multiple texts from Davar3 was fixed by Unicode support in Davar4.
