Thank you for reporting this. The problem occurs because EditPad is a multi-document editor, and the way it handles this tricks AxCrypt into believing the file is no longer used when you open a text file when EditPad is already open.
We’ll be working on a fix for this asap, in the meantime, the workaround is to ensure that EditPad is fully closed before opening another document. Sorry for the inconvenience, we’ll try to have a new build out very soon.
Once again, thank you for reporting this! As a small token of appreciation and perhaps consolation, I’ve added another month of Premium to your AxCrypt ID account.
