For some time I've used MB with a few very helpful toolbar buttons at the top of the main panel. Today I updated to v. 2.4.5349 and the toolbar buttons have disappeared from view.
They seem to still exist in the setup, if I look in the 'Preferences/Layout(1)/toolbar buttons' dialog I can see the configuration for each button is still there. But even if I click on 'Update' and 'Save' this has no effect on making the toolbar buttons appear where they should be.
Am I missing something?
