attaching musescore backup files should be prevented
It seems possible to attach musescore backup files (those starting with a dot and ending with a comma) to forum topic or issues, but these can then not get downloaded. So either attaching them should get prevented or the download needs to get fixed.
Chrome and IE11 (both on Windows 7) give error 403 forbidden
If I do upload such a file, I see a message reg. the file having been renamed for security reasons.
