Every time you log out of RB9, RB9 automatically closes all open tabs (RB9 functions). However, while working in RB9, all functions you open stay open unless you specifically close them by either:
Clicking Close in each window’s upper right corner.
Clicking the X on the right side of each window’s tab.
Clicking [your name on the screen] > Close All Tabs.
> Close All Tabs.
