Parse error with 4.0.1

Sorry about the re-post (if it indeed is) -- it seems our mail server choked today. I upgraded to 4.0.1 today and I started getting parse errors in very strange places (in code that worked perfect with 4.0.0) I get a "Parse error: parse error, expecting ','' or ';'' in classes/stdforms.req on line 164" With line 164 being the first lne in this if statement. if ( empty($sTitle) and isset($this->aEntryerr[$sName]) ) print "$font_form_error Error $font_close <BR> "; Both look perfectly valid and worked fine with PHP 4.0.1 -- I looked and didn't see any changes to empty() or isset() Any ideas? I can't believe that these functions would have been changed in anyway that would effect the above code but hey, I've been wrong about a billion times before :-) Thanks! -Mitch
