Can't map confirm button on Chrome 65.0.3325.181 with extension 12.0.1
I already had the object mapped, but with the lasted version of Chrome is not working, doesn't recognize the object, so I try to map it again but I'm not able to do it
Because of Chrome updating to version 65, you need to apply a patch. See https://support.smartbear.com/downloads/testcomplete/chrome-patches/
