Hi!
I've been a member here for some time and played alot of bullet here. A while ago I started lagging in Live Chess and was continuously 'losing' time, just like you describe it. (Bullet chess is usually where this actually comes to your attention, although it occurs in all your Live Chess games, I'm sure.) This had not been the case previously, so I started a topic in the forums to see what the experiences of other users were. I'll post the link to that topic here, and hopefully your actual problem isn't the same as mine was...

If there are any other details you might deem relevant, feel free to share them and we'll have a look at it.

I don't know what it is but everytime I go play 1 min bullet my mouse starts lagging and time just flies and I lose just about every game these days. It's really frustrating. I know for sure this wasn't happening a few weeks ago. Now, I don't try to bring any controversy over here but is it possible this could be a little hint from the admin "this is what happens if you don't pay membership??" The truth is I quite like this site and I'm even thinking of paying the membership but how do I know, this mysterious lag will disappear? Does anyone else have this problem?
