Error opening dictionary with php pspell function pspell_new

I'm trying to get up and running using the pspell functions on Windows. It seems everything is installed OK. I can use aspell from the Windows command prompt fine. PHP thinks the pspell module is loaded OK. However, when I try to execute the pspell_new function I get the following: - "Warning: PSPELL couldn't open the dictionary. reason: No word lists can be found for the language "en". in ..." I have installed both an english and welsh dictionary and they both work find using aspell from the Windows command prompt. The strange thing is that if I call pspell_new twice then it seems to succeed 2nd time. See code sample and correctsponding output below: - CODE

               /* Set up test data */
                $cWords[0] = "good";
                $cWords[1] = "badd";
                $numWords = count($cWords);

                /* Load the dictionary */
                $pDict = pspell_new("en");
                echo("pDict is $pDict<br>\n");
                $pDict = pspell_new("en");
                echo("pDict is $pDict<br>\n");

                /* Check the words */
                for($i=0; $i<$numWords; $i++)
                {
                    if(pspell_check($pDict, $cWords[$i]))
                        echo("$cWords[$i] is spelled OK<br>\n");
                    else
                        echo("$cWords[$i] is misspelled<br>\n");
                }
