Esc key on gvim 7.2 does not work on windows XP

The Esc key running on gvim 7.2 does not work on a windows XP Professional SP3 computer.

i.e. pressing the "Esc" key does not exit the current insert mode.

"Ctrl-[" does not work either.

The "Tab", "Delete" and "Backspace" keys work as expected.

Please help.

Thanks.
