why when i delete some times app crashes ?
Is it on windows or android? Can you catch exception (try .. except ... showmessage .. end)?
it is on android even try block did not catch any exception
i believe this was fmx problem it self
when you delete something always use a reverse loop ...

  for i := count-1 downto 0 do 
    // delete stuff

Open in new window

otherwise the counter goes beyond the end point
