Cannot input text when using Inspect Elements in Responsive Mode
I'm a Web Developer. I use Opera as my default browser to develop my products. Now I have a problem with the Opera Developer tool. When I open Developer Tool (F12) and use Responsive Mode, sometimes the browser prevents me to type text in textbox, or edit css in Developer tool... It made me feel inconvenient, i must close all Opera windows to make it normal. Do you have any idea about this problem? Please help. Thanks all.
