Hi James, Thanks! However:
1) Your modified BlobWriter.js didn't actually make it through. The attachment was likely stripped. 2) That doesn't matter anyway, as contributions need to be submitted via pull request, not via email / mailing list. If you would like to contribute a change, please submit that change by opening an issue in JIRA describing the bug/feature/etc and then opening a pull request in GitHub containing your change. Please see our contribution guidelines: https://github.com/apache/guacamole-client/blob/master/CONTRIBUTING You can also see this in practice if you look over the git history and past merged pull requests. - Mike On Mon, Jun 24, 2019 at 7:44 PM James Caple <capab...@gmail.com> wrote: > Hi, > > Thanks for the guacamole project.
