Technical issues
Am using Windows 7 and Firefox (27.0.1). Most of the problems that I mentioned earlier are no longer a major issue, although I keep finding myself without sound, even though I regularly clear my cache. I tend to play 3-minute blitz games, so the lack of sound is a major handicap - it means I can't effectively think on my opponent's time, because all my attention is focused on making sure I notice when he/she has moved.
I am becoming increasingly disillusioned with this site, because of technical issues. I have lost count of the number of times I have been cut off mid-game recently; and, even if it's only for a short period, it disrupts my concentration, which is especially important given that I only ever play 3-minute blitz games. I am being cut off despite the fact that I regularly clear my cache, and my connection to all other websites is fine.
In addition, I keep getting distracting alerts from this site about so-and-so's masterclass or whatever, even though I have specifically set my preferences not to receive these alerts.
Other times, when my computer does automatic updates, it's just very slow and clunky on this site, and easy to make mouseslips - which I have made loads of lately - though that's maybe a fault at my end.
Upshot is that over half my recent losses are cos of technical issues!
