Not really, as I go to it, it disappears, but I wouldn't really call it a flash, as then I would not get time to start to move to it.?So just hovering over the notification icon without clicking makes it disappear?
No, but I will try.Looks like I asked this a while back and no solution. Others have reported it. But some think it might be to do with template modifications. Not sure how to diagnose it because there are quite a few addons and I have no idea how any of them modify the templates. Plus I never see them myself.
