Some attachments not downloading with Gmail

Some attachments are inlined, check the 'Inline attachments' checkbox in the 'Search' tab.

Also, a format of attached files that is sent by Outlook (TNEF) is not supported if your mail server does not convert them. These will be ignored by the program. If the attachment still doesn't download, contact issues@gearmage.com.
