Hello Laura Wagner,
AxCrypt will keep track on the opened encrypted files, to update and re-encrypt the same. If we opened the file and updated the contents, then AxCrypt will re-encrypt the updated file.
So after editing the encrypted files, we have to click the broom icon or sign out from the AxCrypt app to re-encrypt the updated files.
We have to close all the instance of the encrypted file(s) opened application.
Please note: If you opened and updated an encrypted text file with notepad and at the same time you had opened an another notepad application also, then you have to close both the opened applications to re-encrypt the encrypted files. You have to close all the opened corresponding applications properly.
After Closing all the opened corresponding applications properly now Broom icon is disable. Now you can sign out/Exit from the AxCrypt app. If not close to the opened Application, the Broom icon is enabled only.(it indicate encrypted file(s) are open).
Still, you are asking any issues, please provide more information about the issue and write a mail to support@axcrypt.net.
