But one user in particularly is regularly sending me MadExcept reports which either have access violation errors or "the application appears to be frozen". In all cases it's during an access of a TListItem which was perfectly valid 10 lines of code up a procedure but suddenly doesn't exist.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;color:#1F497D'>The screenshot created at the same time shows the ListView has no visible items, but I know for a fact there are 30 or more items in the list.
