Preview Pane will work when you first open program. After selecting one or two emails, the previews pane will stop showing the email. When you restart the program, it will work for one or two emails, then stop showing previews.
I have tried deleting the cache, and rebuilding the database. Rebooting the computer makes no difference,
Running latest version of Win 11 and emClient is Version 10.4.4195 (7d32f97). emClient shows it is up to date when running updater.
Any ideas?
