Top rank of board cut off in Vs Computer games

I see a resolved/locked topic on this problem, but I'm also experiencing the same issue.  When I open a game in Vs. Computer, the top row of the board is mostly cut off as pictured below:

This behavior has occurred starting with the first time I accessed it two months ago, and has remained constant since that point.  I have refreshed my browser cache a few times, reboot the machine daily, uninstalled/reinstalled java (even tried an older version to test), reinstalled my browser from the newest stable version, and deactivated any browser extensions but have had no success yet.  I'm using Win 7 Enterprise 64 and Chrome v29.0.1547.49.  Anyone else having this problem, or know of a solution?  Thanks!

Press Control and then scroll down once.

That did the trick-- many thanks to you.

I have the same problem.  Not sure what you mean by press control and "scroll down once." 

I tried scrolling down while pushing the control button but nothing happened. 

Hold ctrl and click - or +
