Size limit for RTF file?

When I added the 6th image to an RTF file, the screen told me the file was too big – but there was no way to leave this screen or delete the file or do anything. No controls. I had to close the app and restart it. Tips?

In older version of DTTG there used to be a limit however this should no longer the case. We will check this and add a fix for the next update.
