Get NumLock working in PuTTY

When using PuTTY to connect to an ESX/Linux over SSH, NumLocks behaves quite strange.  When you try to enter a number your cursor jumps all over the place and you get weird characters.

To use NumLock, fire up PuTTY and select the Terminal – Features item in the Configuration Pane.  Next, check the Disable application keypad mode checkbox.

Click on Session, select the Default Settings saved session and click the Save button.  PuTTY remembers this config from now on.
