Using: AxCrypt-1.7.1878.0 / 32bit / WinXP SP3
I believe the key-file option is meant to be used with storing the key-file on a removable drive (like an USB key). But the location of the key-file is not remembered after removing the usb-key, when logging of or rebooting the system.
This makes the key-file option useless!
Workable usage scenario would be:
* Key-file location persistently set in Axcrypt to file on usb-key
* Usb-key connected: Encryption/Decription/Opening possible
* Usb-key disconnected: "Key-file not found/available" when trying to Encrypt/Decrypt/Open
* Usb-key connected again: Encryption/Decription/Opening possible (WITHOUT having to set the location again)
This would also need an option to set a "Clear Passphrase Memory"-time-limit for clearing the passphrase after X seconds or not remember it at all (= 0 sec.)
