....and he was probably right!
The problem with Flash content soon after browser start up remains exactly the same. The general silence in response to my first post (TFP's problem seems slightly different from mine) would suggest that it's more or less just me. I had wondered if there had been wider developments, of which I had not heard, leading from the predominance of Flash to the appearance of other solutions. Flash is so all-pervasive that it's a big issue which, surely, has to be got right so I expected all sorts of new stuff from those who know so much more than I. I'm not aware of having changed anything likely to be relevant during the past year or more but this problem has appeared only so very recently. Yet, perhaps once a week, I wind up PaleMoon and it all works perfectly - until the next time...
