I am having the same problem as many people in this forum. When I type on my keyboard, the keyboard just starts spitting out repeating characters as if I am holding down on of the keys. It is very annoying and has caused me to lose work as I have had to reboot to stop the pain. I now unplug the keyboard and kill synapse to get it to stop. Since many have complained about this, I am sure you are aware and understand that this is an expensive keyboard that should just work. It least at the basic level of typing. There is something wrong with the hardware/software somewhere and your consumer base is asking for a fix. Please provide the fix for this widespread problem.
