My monitor is oriented vertically (portrait mode). As such, the Results table is truncated at the “5m” column. Similarly, the Live table is truncated at the Weight column. The horizontal scroll bar at the bottom of the window only allows very slight scrolling (not enough to display any additional columns). If there are more entrants (rows) than will fit on the screen then this is the only horizontal scroll bar that is initially displayed.
However, in this case if I use the right vertical scroll bar to scroll to the bottom of the table, there is an additional horizontal scroll bar there (just above the " Powered by phpBB ® Forum Software"). This additional horizontal scroll bar allows all data columns to be displayed.
I hope this helps anyone else who may have been having this problem.
