I've been having similar issues after the update. Adding events or conditions often (not quite always, I think it might only happen with some of them) causes Chrome to ask if I want to stay on page, or just instantly throws me to google with Construct as the next page. This also happens regardless of whether I doubleclick, use 'Next' - button or enter.
I'm on Windows 10 pc. I didn't have this issue pre-update, and it doesn't happen on Firefox (other issues on Firefox, though).
