I am (and have been for some time now) experiencing problems reading some emails. Here are some examples:-
1) Ebay alert emails (generated as a result of setting up a "save this search") - opening the messages causes Pegasus to crash and locks the mailbox. Other email from EBay are fine.
2) Emails from Amazon UK that confirm an order placed (starting "Subject: Your Amazon.co.uk order of ......." have squashed lines and some placed over others. This applies to the Plain Text mode, whilst the HTML Text mode is OK. Other emails from Amazon - eg Dispatch Confirmation are fine.
3) I mentioned the EBay and Amazon above as I Expect most people will be familar with such messages. However, I also regularly have issues with some other emails from organisations that use fancy styles. Fortunately in most cases they offer to read the messages online.
Over to you experts.. :)
