I have been using Scratch with a smartboard without any problems. Then the eMac I was using to project to the smartboard got sick . I swapped it out for another identical model eMac but now when I am trying to demonstrate using any drawing tools the cursor/pointer cannot keep up with my finger tracking across the screen. Instead it randomly jumps to where my finger is creating a straight line but having a severe lag before the line actually appears on the screen. Other drawing programs track fine. Any ideas? I have tried many different screen resolutions with no effect.
