Same here. And this morning it isn't opening at all. I am running it in Opera, which is only partially compatible any more, and I get previews from Windows and just got one yesterday. 

Mine is running under Google Chrome the newest version. Permanent Speed Dial opens in background - visible in the task bar - really for seconds and they disappear than after seconds. These websites are all from my speed dial entries.
That drives me nuts . I am already looking for an alternate to FVD Speed Dial. Hopefully that the makers of FVD Speed Dial can give me a hint what to do. Have checked the settings but cannot find anything to solve this problem.
For response here my email
