I think the problem lies with flash. I constantly have flash crashing on me when I'm playing Tynon. The animated fight scenes take an average of 5-10mins to play out! This is especially annoying because I suspect like you I have installed the latest version of flash. I know this for a fact because the hard drive is less than 4 days old and I've only just installed it.

I'm also noting the worst times I suffer with extreme lag is when the server is at its busiest, suggesting the bandwidth of the server isn't supporting flash to well, causing it to run slowly. I have no issues with flash elsewhere, just Tynon.

Like you Jewels, I've got to grit me teeth and deal with it.
