Wow. I thought that n-key rollover was standard behavior since the 1980s! I thought that you could count on every keyboard to generate "key up" and "key down" events on every press/release of every key, with occasional exceptions (e.g., some implementations of "lock" keys are odd). Any other events or flags (e.g., indications of the modifier keys held down) were just a bit of "icing". I also thought that you could could dependable press/release events even if you held 10 keys at a time, since we have 10 fingers.... Is there a "raw" mode for these keyboards that activates n-key rollover? Dave -- David Young [email protected] Urbana, IL (217) 721-9981
