It seems that the longer one uses any particular browser the more the topics sporadically fail to open. I switched to Firefox from Safari the other day. That worked for a while. Now I'm using Chrome and it is starting to exhibit the same problem.
I haven't had this problem on any other forum that I frequent. It is definitely diminishing my enthusiasm for giving time to this.
My wish is for GS to fix this for good and not just recommend clearing the cache and such which produce mixed results at best.
