HTML5 VPN telnet/ssh keyboard issue

This is a minor issue, but I thought I would post it to see if anybody else has this problem.

I setup an HTML5 VPN telnet/ssh connection. The connection is working fine. I say telnet/ssh because I have the same problem on both types of connections. The problem is that the minus key on the main keyboard doesn't work, but the minus key on the numeric keypad does.
