Dear Hans and Wolfgang (et al),

Unfortunately, I think I may have spoken too soon, as I've run into a small problem. :-)  Using Wolfgang's suggestion of baselinecorrection:

\startbaselinecorrection\setupinterlinespace[line=5ex]
...
\stopbaselinecorrection

I can no longer get footnotes which are in the Arabic paragraph to work. The footnote marker in the text shows up; but that particular footnote does not show at the bottom of the page, though a footnote from text outside of that paragraph do show, with their correct numbering. See attachments for an example.

Kind regards,
Talal
