Hi Stephen, This situation occurs on three computers I can think of, one running NVIDIA, one ATI and one an Intel graphics card. All running the binary drivers from the restricted drivers manager. I don't think this is a graphics problem to be honest... If anyone is interested in testing this. Take a dual-boot laptop/pc. Visit the cartoonito.co.uk website and try a few games using Firefox and the Flash plugin under Windows XP, then under Ubuntu. See what the responsiveness/smoothness of web browser operations, for example: * Type a url into the address bar in Firefox 3. The browser begins to scroll up previously accessed sites as suggestions. Note the performance under both OS's. * Try some of the Flash games mentioned under both OS's. Note the performance of animations etc. I'm sure it's not me going mad! Chris -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.kubuntu.org/UKTeam/
