Resize: changing Units doesn't change Print Size

[dee]

In Resize dialog, uncheck Keep Print Size and change Units number.

What happens: Screen Size changes.

What I expected: Print Size change.

Why I expected it: at the moment, Keep Print Size checkbox has no effect, it always keeps print size. Opposite of keep print size is probably change print size.

Version:
XnView 1.95.4 freshly unpacked from zip, with old config deleted, so everything is reset at defaults (XnView automatically opened initial config dialog).
