Mail merge problem

Question

I have problem implementing MAIL MERGE demo from Oracle WEB site.
1)
The problem is that sometimes I get error on loading document (UPLAD button pressed)
ORA-22835: Buffer too small for CLOB to CHAR or BLOB to RAW conversion (actual: 73187, maximum: 2000):
The problem is that the same document is retrieved and somethimes is OK and sometimes is not
2)
My second questions is: How to upload RTF file which is 1 MB in size?
3)
The final problem is that in Firefox is OK and Explorer allow me only to save the file (and has no extension!!)

Damir,
BTW, Google in searh for :"ORA-22835" return nothing!!!on Unix/Linux you can use the oerr command:
daust:oracle[o1020]> oerr ora 22835
22835, 00000, "Buffer too small for CLOB to CHAR or BLOB to RAW conversion (actual: %s, maximum: %s)"
// *Cause:    An attempt was made to convert CLOB to CHAR or BLOB to RAW, where
//            the LOB size was bigger than the buffer limit for CHAR and RAW
//            types.
//            Note that widths are reported in characters if character length
//            semantics are in effect for the column, otherwise widths are
//            reported in bytes.
// *Action:   Do one of the following:
//            1. Make the LOB smaller before performing the conversion,
//               for example, by using SUBSTR on CLOB
//            2. Use DBMS_LOB.SUBSTR to convert CLOB to CHAR or BLOB to RAW.~Dietmar.
