In MCE and BlueTwo you can not navigate away from attachments in MyMail. I tried it with all 4 skins and it works in Metal and Naley, in MCE and BlueTwo you can not navigate away.

To reproduce:
* Setup MyMail and send an e-mail with attachment to that account
* Start MP
* Goto My Mail and view the mail
* Navigate to the attachment
* Try to navigate away from the attachment
* That doesn't work
