Not all third party extensions support inline editing. For most this shouldn't be a problem as they will not be editable, however some third party extensions may behave eractically so you can disable inline edting for those extensions, by following the steps below.

1.  Navigate to 'Components' > 'Ark Editor' > and click on the 'Options' button.

This will take you to the 'Ark Editor Configuration' screen as seen below.

2. Navigate to 'Enable in Components' and click on the 'X' of the component/s, you wish to disable inline editing for.
3. Finally, click on the 'Save' button.

Inline editing will now be disabled for your chosen component/s.
