Here is another,
If you click on "MyAssistant" it only controls that 'Tab', if you open a 'Topic' by right click and selection 'OpenNewTab' then eventually closing the original 'Tab', "MA" was open in, then bring "MA" back to the front of your desktop it will no longer work. It is tied to the original 'Tab' where it was open first. You have to close "MA" and open it again in another 'Tab' and keep it open because it will only work with that 'Tab'.
See if that is clear, or maybe mud,
