Why does a second copy of Exl-Plan load when I click on Exl-Plans toolbar?
This arises because the second copy has the same file name as the first copy but is located in different folder. To resolve, close the second copy and then reset the toolbar for the first copy by *Tools/Setup | Reset Toolbar Buttons. To prevent this recurring, don’t use two different Exl-Plan files with the same file names at the same time.
