SENDMAIL - ASPRUNNER PRO 6.2 BUILD 4689

This is using ASPRUNNER PRO 6.2 build 4689. My site has several modules that send email out after certain activities. All sendmail functions worked fine with 6.0. After I changed to 6.2, one sendmail function is not working. Sendmail works fine in all other module except in event.asp. It doesn't give any error, it just seems like bypassed the sendmail statement. I tried to change it to runner_mail using the format in "Help", but still not working. This is kicking my rear. The statement is : sendmail emailadd, subject, message. Same format thru out the pages.
