zbook 17 G3
Microsoft Windows 7 (64-bit)

Received the zbook 5 days ago with win 10.  Downgraded to win 7 (no errors in process)  with hotkeys driver loaded, f5 & f6 keys (and others) throw this hpCaslNotification error with hex codes. First it only happened of I pressed the keys fast.  But each time I pressed the ker and hourglass would appear.  If I waited for it to go away before pressing again, the error would not throw.  But I aso noticed that with the stickey keys active, they would not make a sound as expected.  I removed the hotkey driver and eventually the stickey keys would sound, but then the monitor couldn't be adjusted.  But installing the hotkey consistantly produces the error.  Now it does it with one press.  I have re-installed win7 2x.
