1) Set the option TLB Settings->Toolbar->General->Minimum size into any number equal or more then number of buttons on your toolbar (you can set it into 100 to be sure all right). This option will prevent the creating of menu with two arrows. TLB shows this menu if there are no room for buttons.
2) Make the width of the toolbar into the optimal when there are no drive I:

Now when you plug the drive I: TLB will expand the toolbar.
