I have seen quite a few posts on using the 1.9 dev version for production uses. How stable is it? Is it really ready for production? I would like to use it.. but I never ever put beta packages in procution.. but then again.. I'm always dealing with Microsoft :)

As for getting rid of your current intermediate files, I'd rebuild from scratch just to ensure things are OK. -Yonik Now hiring -- http://tinyurl.com/7m67g On 10/21/05, Roxana Angheluta <[EMAIL PROTECTED]> wrote: > > Thank you, Yonik, it seems this is the case. > What can we do in this case?
