I'm saving an Excel 2010 workbook as PDF to Sharepoint Foundation 2011, either with 'save as' and navigating to the Sharepoint library, or with 'Save and Send' to Sharepoint.

Question - how do you change the default sort order for the current files in the library in the Save as window? Whenever I open the save as window, the files are sorted oldest first. The default view for the library is newest first, but that doesn't seem to apply to the save as window. Changing the view of the library in Explorer makes no difference either. What am I missing...?
