Otherwise just turn off automatic redirects (they are only needed if you constantly change you product / category titles - or are migrating an existing store with well established URLs).

The next version will have better support for scripts calling application_top which are not coded as zen cart pages. Not really sure of the logic behind not coding these as zen cart pages (yet calling application_top)... Permanent work around will probably be optional.. Adding an addition file lookup (minor performance hit).
Thanks I have just turned off the redirects and that works OK
