Cannot Suspend vi with Ctrl-Z

Question

It's on an AIX 6.1 connected via PuTTY 0.65.

If I open a file and hit Ctrl-Z then. It works 1st. But when I switch back and hit Ctrl-Z again. A square cursor jumps to the bottom. I can type something but it can't be escaped to vi's command mode.

It's frustrating and I have to open up another session to kill the vi.
