I have been reading a password protected file opened from Dropbox. This file closed by itself several times without notice! What is happening?
Sorry for the delay in response.
Please check if the application is updated to the latest patch released.
Could you please confirm if it is the file that close or the application.
Did you check if you experience the issue with other files as well?
