// B2021-003: random crash on lbSrchResultsIncTrans selection. Originally, only ItemClicked was used
// to track how many items in the list were checked. However, this gets called for both
// the clicked & checked events, so the count of checked items was not accurate (this count,
// IncTransSelectedCount was incremented/decremented when event occurred). The reason that the clicked
// event needs to be used is that the sender contains the bound item (proms item) but the checked
// event does not, so both are needed. The tracking of checked items is done to enable/disable
// the 'Convert Selected to Text' button. The fix was to flag from the ItemChecked event that the
// item was checked not just selected, so that the code in Clicked only runs for a check event.
