We have replaced the existing email editor with a new editor that better handles tables and corrects a few of the issues with the prior editor.
It's currently in limited release and you can get an update ahead of the general release by emailing support@trailblz.com and requesting it.
Current version (or legacy if you have already been upgraded):

New version:

Some of the enhancements include:
- Publish your email on Facebook, LinkedIn, Google Plus and/or Twitter

- A preview button
- A working Undo button (YEAH!!)
- Search and Replace and Spell Check
- Better formatted and thus more easily read source code
