Occasionally, when using Thunderbird to check my linked Hotmail account messages the preview pane displays the the following; '''----boundary_75e27897dff0419baf014a41bcb9dc32--''' This happens on all messages that have downloaded since my last login to Thunderbird. All other accounts behave as usual and show the contents of the messages. I can open Hotmail and view the messages without issue. Once I have opened Hotmail and then return to the Thunderbird account everything functions properly, but the previous messages with the error remain unchanged when selecting to preview the contents. Anyone have any knowledge about this as an issue or a solution?
