On certain sites using Local Storage, a pop-up appears instead of the Flash-based application, with the following message:
Adobe Flash Player Settings Local Storage www.example.com is requesting permission to store information on your computer. Requested: up to 1 MB Currently Used: 101 KB [Folder icon] [Allow] [Deny]
And it's impossible to click either button. That is, clicking has no effect. Therefore, the application can't be used any more.
How to allow or deny this setting?
