Printing attachments error 1155

I have downloaded Build 1.3.1104.

When printing attachments I always getthe error:
Error: problem executing print verb on file
C:\\...\Temo\winmail.dat, error: 1155

I have tried attaching .doc, .jpg, .pdf, and .txt files and I always get the same error. It seems that MailPrint is always converting attachments to winmail.dat and produces that error.

I have tried sending the .dat file directly to the printer, but that file is textual junk.

P.S. I understand printing PDF files may be problematic since I only have the Reader installed on my PC. However, I have Word, and text and JPEG readers on my PC whicg are associated with the appropriate files. Still -- can't print any of these atachements.

Microsoft have an article on dealing with this at http://support.microsoft.com/kb/138053
