I have a control called MyDataGridView, and the property
ContextMenuStrip is set to ContextMenu Control.

The problem is ... when I write click on MyDataGridView, the context
menu comes up in edit mode.  That is, I can click on an item and edit
it.  Also, the menu does not go away after I click on it.

One big complication.  As I said, MyDataGridView is a user-control
that extends the DataGridViewControl.  It overrides the mousedown
event.  In the override, I call a new Event ("MouseDownPrep") in which
I let the subscriber set a variable in the Args object, that cancels
the MouseDown event.  Hope that makes sense.

Any ideas on how to fix this?
