Hello,
I've always used Skritter with Safari and a Bamboo on Mac OS X with flawless performance and fluidity, however, since the latest Safari (/OSX?) update, the framerate has decreased significantly to the point that every few seconds it doesn't register a portion of a stroke or typed pinyin. I've tried reinstalling Safari, the Flash player, and the Wacom plugin (as well as disabling the plugin) all to no avail. I've also tried switching over to Chrome, only to find that it is also pretty unresponsive. Any suggestions would be greatly appreciated. Thanks!
