update Opera 6/2014 added ad pop up window
The pop up window that can not be blocked is a problem. Yes you can shrink it on the screen but PRINT the page and guess what!!!! The pop up ad is printed in the middle of the page over all the information that you wanted.
[Mod note: thread moved to Windows forum.]
What is your Opera current version and build number? And did you obtain it by an automatic Opera update or by manually downloading/installing it - and if the latter, from where did you get it? Otherwise, have you downloaded/installed any other software (especially freeware) at or since obtaining your current Opera version?
