Well, it's not the statusbar, which is at the bottom of your screen (if activated), but the Info Box, which contents change depending on the selected tool.
The Info Box contains different settings, which take up some screen space. If this space gets smaller, they don't fit into any more, but extend beyond the border - the Info Box does not resize with the window width.
You can optimize your workspace in many different ways in Archicad. Maybe going through the help pages can help you with that - here is the section about the work environment settings:
Also, the Info Box is scrollable, but many mice do not have an easy horizontal scroll function. It's just one more reason not to use a horizontal Info Box. Instead, drag the Info Box to the side of the screen (left is a common location) where it is both more visible/useful... and can be scrolled with the vertical mouse wheel or touch function.
