why are some of my keys not working on em client????

my delete, backspace, arrow keys are not working in the subject and To box- please help as it is driving me insane!

Hello, not quite sure what you’re referring to, can you please specify the application’s behaviour or make a screenshot of the issue? What version of eM Client are you currently using on your computer, can you please check the exact release number in Help > About?

Make sure to update your eM Client to the latest release and that all system updates have been installed, eM Client is running on the .NET framework so please make sure you have .NET 4.5.2 installed on your computer and that your Internet Explorer is also updated to the latest release (even if you’re using a different browser for daily use).
