I was 80% complete on a GF survey about smartphones when I reached a page where you were supposed to click on icons and drag them to a number line. I couldn't click and drag the icons. (There were several of these type questions in the survey, and the others had worked fine.) I refreshed the page, but it still wouldn't work. I had to close out of the survey, and now there are no more GF options for me.

(This is more a technical problem than a surveys not crediting issue, but I didn't know where else to put it and wanted everyone to be aware.)
