I was able to get rid of the ghost icon only by restarting. I have used axcrypt successfully since, with existing encrypted files, but was able to recreate the problem by generating a test excel file, and encrypting it. The result is an encrypted file icon, as expected, and a normal-looking icon of the original excel file – but that icon cannot be opened (or deleted). I have screenshots of this, and will try to send them to you, but am not sure how – my first try (trying to copy them into a message like this) did not work. And lost the message. So I will send this, and then try again with the screenshots.
