Summary: While using Google Chrome, the Guided Editor overflows window width and prevents the user from being able to view the right-side buttons for adding, moving, and deleting LHS and RHS elements.
Cause: While opening an existing .gre.drl or .gre.dslr rule in the Guided Editor, the Chrome browser hides the right-side buttons for LHS and RHS elements. When creating a new .gre.drl or .gre.dslr rule, the green plus buttons are visible within the visible window in Google Chrome; however, adding any LHS (WHEN) or RHS (THEN) element will move the green plus buttons outside of the visible window.
Consequence: The overflowed window width in the Google Chrome browser encumbers the user from being able to select the LHS and RHS element buttons.
Workaround: A current workaround is to open Guided Editor with a Firefox browser while working with .gre.drl or .gre.dslr rules.
Result: Using the Firefox browser allows the user to select the right-side buttons for adding, moving, and deleting LHS and RHS elements.
