There is a bug in the currently running version of TWiki.org, that does not appear in the Dec 2001 release: a %<nop>FORMFIELD% inside a <pre> messes up the preview view, giving you the garbage seen in SandBox39 on save...

Colas - can you re-create the problem, or close the bug?

below is my attempt at reproducing the issue from the description above
