PeopleCode AddAttachment fails to upload JPG file

Hi guys.

I was wondering if anybody else is having problems uploading a JPG image file using the AddAttachment function when the extension is upper case?

I can upload the file just fine if the extension is lower case but if it is upper case the AddAttachment fails to load and does not report an error back.

I think it is wort nothing that I am using the AddAttachment within the delivered add_attachment funtion.

Declare Function add_attachment PeopleCode FILE_ATTACH_WRK.ATTACHADD FieldChange;

Please note that when calling the add_attachment function I have been using message level 1 to display all messages.
