No sign of this problem here. My problems (also pop-ups that take over the session, requiring re-start), have been with the Mobile Enhanced version running on an iPhone.
Additionally, also with Mobile Enhanced version, I've been seeing a sharp uptick in pages on this site crashing repeatedly with a message like "this webpage has encountered a problem and needs reloading". I can see it coming when tapping the phone does nothing (frozen), then about 5-7 seconds later, the page gets re-loaded. There have been times when this has logged me out, and other times where I lost my post (but a Draft is usually retrievable).
