If you are starting eM Client from the Windows Start menu, you should only be clicking once on the icon. Maybe you are starting from a desktop icon though.
But you can try reinstalling and see if there is any difference.
Close and uninstall eM Client, making sure NOT to delete the database folder when asked. That will ensure all your data and settings are there later.
If it exists, delete the C:\Program Files (x86)\eM Client folder.
