[Xerte] Re: . Xerte 2.n - Page Wizards (April 2011 release)

[Kemp Johnathan]

Must be a new usage of the word odious, never used it as an alternative to
"helpful" before.

Just checked, not so much as a sniff (to keep things in like vein)

I wondered if it might be something to do with the code that processes the
xwd and xml files to generate and populate the wizard.

Kind regards

Johnathan
