This is because the ampersand has been converted to the equivalent HTML code.<\/p>\n

You can solve this problem by changing one line in latex.php<\/strong>. In
\n\/\/ $latex_formula = str_replace(\"& #38;\",\"&\",$latex_formula);<\/code>
\nremove the comment \/\/<\/code> and change 38<\/code> to 038<\/code> so that the line reads
\n$latex_formula = str_replace(\"& #038;\",\"&\",$latex_formula);<\/code>
\nPlease note: In order to show the code here I have had to introduce a space between & and #. That space should not<\/em> be there in latex.php<\/strong><\/font><\/p>\n

Other odd effects can be dealt with similarly.
\nIf you see a8217; instead of a’ then either
\n1. use ^\\prime in your LaTeX code and\/or<\/em>
\n2. add the line (removing the space between & and #<\/font>)
\n$latex_formula = str_replace(\"& #8217;\",\"'\",$latex_formula);<\/code>
\nin the same place as the previous one in latex.php<\/strong><\/p>\n

Both alterations appear in the latest download.<\/p>\n
