On adding projects to the menu and after that deselecting projects from customize menu bug: projects menu item does not disapear from the menu and project field is always visable in the transaction from (just before the division field)
This is not a bug. Check if you have any projects listed under projects. Delete all these (inactive is not good enough if you want to remove projects altogether). You will see that the tab disappears when the last one is deleted and if projects was disabled in settings.
