Testing for Adobe Shockwave player plugin does not give results, it's blankOpera for Windows
Noticed for a while now that testing for the shockwave player installation (https://www.adobe.com/shockwave/welcome/) does not render the result of test...in fact it pops an irregular 'shockwave director plugin is slow' dialog box, like it's trying to handle it. Tested on all other main browsers (IE, Firefox, Chrome) and no issues. Just thought you'd like to know and perhaps address it.
