I have a sys tray icon with a context menu set.  I only want to allow a
right-click on the icon if the control key is pressed with the right-click
is done.

I can't figure out how to do this?  I've tried overriding a lot of the
events and attempted at things like Visible and Enabled, but I can't seem to
just not allow (i.e. ignore) a right-click on the sys tray icon.

I can override events and check the right click event (and the control key),
but I can't figure out how to then just indicate to ignore the click if
control is pressed.
