problem with keyboard during installation

I am trying to install a new system using FreeBSD-10.0-CURRENT-amd64-release.iso.xz (from 
https://snapshots.glenbarber.us/Latest/).  I am having a problem with the 
keyboard.  I have tried all possible options of US keyboards, and also the 
option not to change the keyboard.  The problem specifically is that when I try to change the 
amount of space of a partition I am unable to navigate using the arrow keys.

When I try to use the right arrow key to move the cursor, it moves the 
cursor to the OK button.  But that is not what I want to do.  I want to 
setup the partitions manually, but the keys will not allow me to.

I know there have been a lot of changes to the install code recently, 
has anyone else seen this behavior?  I have tried wired and wireless USB 
keyboards, I am currently typing this from the wireless keyboard. so I know it works.
There was some discussion concerning this here:

Any help would be appreciated.  Thanks in advance.
