New Issues

Lightning is broken in SeaMonkey 2.22.1 (bug 941217). This should be fixed in SeaMonkey 2.23.
Trying to send an email via SeaMonkey from an external application using MAPI is no longer working (bug 913493). This will be fixed in SeaMonkey 2.23.
Tree rows, e.g. those for MailNews folders and threads or in the Bookmarks Manager, show extra spacing with the Default theme on Windows with Aero active (bug 927779). Workaround: Add the following rule to userChrome.css:
```
    treechildren:not(.autocomplete-treebody)::-moz-tree-row {
      height: 1.3em !important;
      border-width: 1px !important;
    }
```
This will be fixed in SeaMonkey 2.23.
