Why does my listbox disable (go blank and gray) when my combobox-interactive-change sets a new filter to the freetable? The code in the interactive change reads:
if this.value = "All"
set filter to
go top
thisform.refresh
else && if there is a value other than "All" which will match some records
set filter to Field1 = this.value
go top
thisform.refresh
endif
