Why do I receive the message "Suspicious characters found in selected filename, will not process it" when I try to add an attachment?
When adding attachments to secure notes, we do not allow the characters ; ! $ * ? & ; we also check for characters created by keystrokes such as ctrl-A, ctrl-B , etc. The reason we do not allow these characters is because they can cause security issues on Linux/Unix platforms.
