Dropbox fix
Response from support concerning Dropbox issues. Doing this fixed my problems.
Thank you for the update. There is a current issue whereby image files (jpeg, gif, png, etc), if present in the root folder of a Dropbox account, can cause the app to crash when accessing the cloud service. This does not happen if the images are held in a subfolder. To circumvent the issue you can move image files to a folder, and the app will behave as normal. We are in the process of producing a fix for this issue which we shall include in a new version of the app as soon as is practical.
