PDF Attachment not showing filled information

more options

I have noticed a problem that could be potentially dangerous. I received an email with a PDF attachment. The attachment contained a number of filled in information in predefined preset fields of the document. When I opened the attachment, some of the fields did not show the filled information, the corresponding fields were shown as blank. When I opened the same attachment using the Windows Outlook desktop Application, all the information was displayed correctly. Changing the Action field in the Thunderbird settings under Datatype and Attachment to open the PDF with EDGE, the information in the attachment was displayed correctly again in the preview mode of Thunderbird. There seems to be a limitation within the PDF preview mode in case the standards settings are used: this should be corrected as it can cause serious problems, if important information is not displayed.
