Clicking the forum's top left icon does not always work

Often it works - refreshes the forum’s main page or takes me back to it from a particular thread, but increasingly often it has no effect at all, and I have to use the browser’s URL and refresh features. (Using Firefox.)

Okay, thanks for the report. Do you mean the “Latest” button a different one?

Latest seems to be the default display mode, which is good. I only seldom need to press that link.

The “icon” I was referring to is the “logo” (is it your logo?) on the top left - the dark solid rectangle with the text “” in white.
