Shell – ksh Auto-Completion PuTTY Configuration

I'm having a bit of a problem configuring my PuTTY client to work with the auto-completion feature in the ksh shell.

I do a listing on the root with the directories /home and /homeroot and it returns the directories in a list just fine. I can't select it, though, by hitting X = (where X is the number).

/home/nitrodist>ls /h        #hits esc + =
1) home/
2) homeroot/
                             #hits 2 + = for the 'homeroot' dir
1) home/
2) homeroot/
                             #hits just the '=' key.
1) home/
2) homeroot/

Any ideas? I've su -'d to another user who can actually do it with their PuTTY session and I can't do it there, which makes me think it's a PuTTY configuration issue. This is running on a ksh93 shell on HP-UX, if that makes any difference.

Here's my ksh config:
