Excel attachment not rendering correctly in Mail but fine on iPod touch
Some attachments (most notably Excel files) that I've been receiving lately (last month or so) have not showed up correctly as attachments in Mail (currently using v. 4.4). In the list view it shows the paperclip icon but when I click on the message the preview pane shows what I assume is mime code or something. If I check the same message on my iPod touch, the attachment shows up at the bottom of the message as an attached file icon (correctly identified as an Excel spreadsheet). Suggestions?
