Help with sablot and php_sablot extensions please.

I am running Win98SE with Apache, using PHP as a server module. PHP will not load sablot.dll or php_sabot.dll extensions because of another library that can't be found. No doubt it's something silly I've missed out of the php.ini file but I've been over it several times and I still don't get it. I am hoping to set up server-side XML and XSLT in order to send the input from a form as HTML in an email to myself. I have it all pretty much worked out but I can't test it locally unless I get the extension working. Note that the php_domxml extension is loading with no problem. I would copy the php.ini file contents in here but the mail would then be too big to be accepted by the list mailer daemon. Thanks in advance Peter Manchester
