Hi Mike,

on grid control, if you press SHIFT / CTRL / ALT , MouseWhell event not fired.

It is a bug.

In fact, on Debug with Track Event Logging ON , on Output window, MouseWhell() it appears correctly, BUT Track Event Logging it is much unreliable.

Question ?
Track Event Logging from where it reads the events,
if a lot often these are not taken place?
