@cyberix3d does this works fine in Chrome or other browser? I'm not sure if this is flash issue or browser issue.

[cyberix3d]

Yes, it works fine in Chrome, and also in Firefox 51.0.1 with the same Flash Player.

Probably an issue to report on Bugzilla, if it's not a mistake of the Web site.
No obvious candidate in this Mouse Flash Player search.
