This is the second day of this happening. Unable to fix it.
What happens when you click Reply?
What version of eM Client and Windows are you using Len?
Found a patch to download on the forum as someone had the same issue. It fixed the problem. The reply window just opens up behind the main window. I’m using the lastest version and running Windows 10.
You should not need to patch the current version. Any patches on the forum would have been for older versions.
Check that you have the latest version from http://www.emclient.com/release-history
