If a reboot of your computer doesn't fix it (as it does for the vast majority of issues we encounter),
A public Github has been created for logging issues (bugs). If you experience a problem, you can create a bug there. Before you create an issue, do a quick search to see if the issue you are reporting might already be present. When you do create an issue, read the template carefully. A report that just says "it doesn't work", is not helpful. Screenshots, log files, steps to reproduce. All of those things make a huge difference.
