Hi Noella,
Thank you again for your feedback! I just let our developer know about this, and he's going to implement a confirmation dialog after you click on an attachment to delete it in the record edit view. That will be implemented in the 6.1 release.

For the PC version of mSecure, I wish there was an undo button or a warning when you click on an attachment while editing a record. As it stands, it automatically deletes the attachment if you click on it...yikes!!!
