newbie/strange problem with vi

Installed uboot with http://jeff.doozan.com/debian/uboot/
installed debian squeeze with http://jeff.doozan.com/debian/uboot/
reboot to debian fine but have an issue with vi
When I start vi from putty on a Win7 machine, I can use the cursor keys to move around on my file. However, I can't do that any more if vi is in insert mode. upper arrow will insert a blank line over the cursor and display a upper A. Down arrow will do the same except B is displayed. Left arrow is D and right arrow is C.
With the same putty, I can use vi fine with another machine.
Is this a configuration issue?
Thanks.

Have you already installed vim on your dockstar? vim replaces vi with a more functional version.
apt-get install vim

No, I have not tried vim because I am using nano. I just surprised why cursor keys work when in non-insert mode but not in insert mode.

I just installed vim and it works and has no issues with cursor keys! Thanks.
