I haven't updated wingross 7 for about 8 months, could that have anything to do with it?
I have NO PROBLEM with Mozilla FireFox, Google Chrome, Opera and Vivaldi of which I run all of them at the same time, even until Avast Secure Browser failed on me. I quit all of those browsers including ASB to re-boot my computer which had been running for about 8 days, and all except ASB would start back up again.
