[Zope] Customizing Error pages?

[Alec Munro]

In response to Paul Winkler (because I'm no good with mailing lists).

I've tried modifying standard_error_message, and it seems like it works 
sometimes. My impression of it is that standard_error message picks up 
Zope Errors, but there is some other template somewhere which picks up 
Site Errors. Interestingly enough, the Site Errors template will 
attempt, to a degree, to make use of the standard_error_message.

I guess I will do some searching and see if a solution to this pops up.

Thanks,

Alec
