I've downloaded that Beta, but still can't get reliable service. It works sometimes, but more often than not I have to keep clicking the "Remote Control" button otherwise I just get a blank white screen. It seems to work best if I click it twice - slower than a double click, about 250ms - 500ms.
This may all be due to something else but it happens on all sites (I have 55 of them) and it always works OK with IE and Firefox.
I saw a trick on a thread somewhere that showed a trick of copying files from the Firefox folder into Chrome or was it into LogMeIn?). This worked fine but after a recent upgrade of LogMeIn this stopped working so well. I can't find that link now that explained what to do.
