i am trying to open a google search inside an iframe. it was working until recently but something happened.
this can be tested here: http://jsfiddle.net/patrioticcow
We are seeing the same problem - this time with google in a standard frame. It was fine a couple of months ago, now it's not working. I think that Google just changed the rules... Not a very open thing to do.
I'd suggest that you run what was in the iframe as a separate child window or new tab - not sure if this will give you the result you wanted.
