Outlook 2010 message files are not viewed in HTML

[andyh]

Dear kinook,

I updated to v5.1.0.12.
I use the portable version.

Now imported Outlook message files are not viewed in HTML. Instead of this the html source code is displayed. If I copy and paste the message text into UR it works fine.

Edit: Copying and pasting the message text is *not* working. After reloading the message item the html source code is displayed.

How can I fix it?
