I’ve never heard of a problem with Xing out popups. Do you mind if I ask what browser you are using?
Maybe wasn’t clear ... my browser is 11+ Microsoft. Not the best for avoiding malware and viruses. The ‘X’ out may not be infected yet but (imho) is coming. I have no problem ‘X’ing out, if I do, but have started going around ‘X’ing out. Attempting to make a habit of doing such and avoiding ‘X’ing out. Too many setups and coding of the ‘X’ out with malware and viruses would not be that difficult (imho).
