Hello!
Opera Turbo doesn't work in Opera 38.0.2220.41 with KIS/KAV/2016/2017 instaleld. Windows 8.1 x64 with latest updates. Posting here since I don't know who is to blame for this incompatibility. Steps to reproduce:
Install KIS/KAV/2016/2017
Launch Opera 38, enable Opera Turbo, go to any http site (www.mozillazine.org as an example). Result: contents of the adress bar are erased, blank screen instead of the webpage.
Bug is not reproduced with Opera 36 or https websites. Thank you.
