We have fixed this problem with v3.4.3 and replaced the Mezzmo v3.4.3 Auto Update package and Mezzmo full installer on our web site.

If you have already applied the v3.4.3 update, then please download the full installer from our web site (www.mezzmo.com) and run it (do not uninstall your existing Mezzmo). When the Mezzmo installer prompts you to do a Repair, click Yes. After the repair has completed, your Mezzmo v3.4.3 will be up-to-date and the issues should be fixed.
