I've already replied to this thread, saying that although I wasn't finding support as good as it used to be, I was still finding it perfectly adequate.
But I hadn't actually used Technical Support for some months.
However, on Sunday evening I raised a support case, and when I got up on Monday morning I found it had been replied to.
It wasn't very complicated, and just needed deleting the preference file, but it was still a very fast response.
The problem was the keyword filter panel being cut off down one edge so you couldn't the see the radio button or the number of files for each keyword.
