Yes I was wrong here.

It is of course, my testing was wrong.

Yes, right, my claim is true for 1.5, 1.5.1 does it.

I could not find an attachment, just the line above.
Meanwhile I thought had all the __ things and raise statements out
and got it running so far. Perhaps I missed something, since I never
got the admin pages to work. I could not edit any list, and I gave up.

Probably my fault, although - who did it get to run under Redhat
Linux? Can someone give me a working Linux version for the Starship?
I'm afraid to re-invent the wheel.

How do I get at the CVS tree?

thanks&cheers - pirx
