Save Page WE is designed to save a web page as currently displayed. This is almost identical UnMHT's save 'Current State'. There is currently no equivalent to UnMHT's save 'Original File'. It would be possible to add this feature to Save Page WE, but not many users have requested this feature.

With regards to Save Page WE not saving pages, please can you provide a link to a page that is not saved. Please email to: dw-dev@gmx.com
