Your comment Save extension is no longer working under Windows Professional 8.1 on the http://www.mysticboard.com/ site on my dual boot set-up machine with 4GB of RAM (two separate physical hard drives).
My browser is Google Chrome Version 35.0.1916.114 m.
Interestingly on the same machine it still works under Windows 7 Ultimate Edition SP1 on this web site.
I have tried clearing the comment cache, but the postings are no longer saved as they once were under the original Windows 8.
Which makes me think that the problem is related to something different in the way that the extension, browser and OS interact with each other.
Any ideas?
Thanks!
