I appear to be the only other person who ran into this problem! In my case, I was clearing the current selections in the CellMouseDown handler and selecting the row that was just clicked on. I was doing this in order to allow a right-click to select a row. It was working fine, as long as Control was not pressed. I protected the code with a check for the Control key, and that worked:

if ((Control.ModifierKeys & Keys.Control) == 0)
{
    myDataGrid.ClearSelection();
    // ... additional code....
}

None of the other grids in our application had this issue, so maybe this is your situation, too?
