<font face="Helvetica, Arial, sans-serif">TexShop (4.55 and previous
versions) is giving an error including graphics with message:<br>
<br>
<br>
<b>Runaway argument?</b><b><br>
</b><b>"xxx.pdf" \edef \Gin@ext {\Gin@temp }\fi \def \Gin@temp
{.png}</b><b><br>
</b><b>\ifx \ETC •</b><b><br>
</b><b>./TexFile.tex :105: Paragraph ended before \@tempa was
complete.</b><b><br>
</b><b><to be read again></b><b><br>
</b><br>
where line 105 of the input .tex file "TexFile" reads:<br>
<br>
<b> \includegraphics[width=.2\textwidth]{xxx}</b><br>
<br>
and xxx is a .pdf file. <br>
<br>
This problem occurs on three different macs, macbookpro, macbook
air, and iMac.<br>
<br>
I do not have this problem with Overleaf and cannot seem to find a
solution online. <br>
<br>
Help would be greatly appreciated. JG<br>
