[NTG-context] Page Numbering using IncludePicture from simple slides
Hi, I love the IncludePicture command from simple slides but now I've got a picture which I want to show stepwise. Therefore I created two pictures a simplified version and the full version. I just place them right one after the other. Now it would be perfect if I could force context not to increase the page number counter for the second image because in my handout I will only include the full picture and at the moment the additional slide is messing up my page numbers. Any suggestions? Thanks!

Hi there,
like in January (see mail by Mari), the latest beta produces only
empty pages with 2UP imposition schema; others work (tested 2SIDE

e.g.

\setuppagenumbering [alternative=doublesided,location=footer]
\setuplayout [margin=0pt,width=fit]
\setupbackgrounds [text][text][background=screen,backgroundscreen=0.7]

Any news on that? Today's beta still is buggy.
Unfortunately I need 2UP imposition urgently.
