We are having a problem similar to what others have posted. When a teacher writes a letter on the board, one part of the letter is not writing. For example, the top flag of an F or the leg of an L. The pen will write properly when making a big arc or circle or a lot of continuous squiggles.
We've tried different pens, reinstalling drivers cleanly, same for app, etc. We have no USB booster and have a single cable running to board. Given that I can bring another computer to the same board and NOT have the problem, we can reasonably look at the computer itself.
Computer is OS X 10.8 with no available updates - meaning it's fully up to date.
Board firmware is 8.04
Driver is 5.9.27
App is 1.8.64351
Serial of board is C1006030104
What next for solution to fix this?
