Following moderators’ and administrators’ advice to clean out the temporary file clutter on my PC certainly worked, and I’ve no great problems logging in since. It had a little wobble the other day, but I am not sure if that was its own hiccup or my error, perhaps not pressing the “Not a robot” thing.
This experience could be related to other users’ different ones by making me ask if the site is very sensitive to instruments, OS and browser.
However it’s now found a new way to annoy me – putting up the wretched “cookie” request every time. Why the heck has this section developed amnesia? It did not do that previously. After choosing my preferences (Functional only) a few times I now pick “Reject All”, so far without problems. I still see the ads, so our suppliers are not invisible to me.
