Problem: The bookmarks, mails etc. from older versions (and from Netscape 6/7 and Mozilla) don't show up in version 0.8.
Reason: Version 0.6-pre Windows shared its base profile folder with (Mozilla and) Netscape 6. This caused major problems, from resetted preferences to a completely disfunctional user interface. Thus, version 0.8 and following versions use a base profile folder specific to Beonex Communicator. However, no import routines for the old profiles have been written.
Workaround:
To import your old profile manually, copy the contents of the old profile folder (on your harddisk) to the new one (automatically created).
Then, delete localstore.rdf and the sub-folder chrome and adjust the path names in prefs.js.
Problem:
Some messages in Mailnews show no content at all, if View|Message Body as|As Plaintext is activated.
The problematic messages are usually bulk mail or spam.
Reason: This is a remaining bug in the new As Plaintext feature.
Workaround:
Use the Simple HTML mode. It's much better, anyways, and does what you probably really want.
This is a bug in this release.
