Comments in other user forums (re Chrome) indicate it is getting more prevalent; some report it in Trip Advisor and other sites also. talking to someone who knows their way around PCs suggests this is an issue between Win10 and Chrome taking effect in some forums.
I have heard nothing from MSW Admin etc whether they have reported the issues to Google/MS and it seems Google/MS are doing nothing (that I have found anyway). There is nothing physically MSW can do to fix it I think; but using their voice through the software they use, Googgle would be more likely to listen than to minor users like us I don't know whether the time out problem is related but it all seems to have started with one of the recent Win10 updates.
At the moment I am muddling through by ignoring the links in the notifications drop-down list, and not using the buttons (Dot or Star) to the left of each topic as these seem to be the only items affecting/causing the issue. it makes things slower as I use the star as an indicator of a new reply/post and then click on the last page link for that topic. You have to scroll down to read but at least you can access it,
A real 'pain' and if there is nothing done about it soon I think Google will be losing some users?
