Description David Moore 2014-04-25 12:16:00 UTC
ComboBox is initially created with no ComboBoxStyle selected.  ComboBoxStyle is changed to DropDownList shortly thereafter. The user selects an entry on the ComboBox and then moves the focus to another control.  The ComboBox text immediately switches back to the initial value that appeared before the user changed it.

This appears to be caused by internal ComboTextBox class lost focus handler being called long after the ComboTextBox has been disposed.
