Subject: Deleting List Object Array before Abrupt Close
> I am able to delete a list object array (containing the strings in shown
in the list) by calling a function to do when "Exit" is selected and the
form on which the list appears is exited via a menu or an object related
function that causes another form to appear. If I try to call the same
function to free the memory associated with the list object array from a
FrmCloseForm event, which happens when the user abruptly transfers from the
program to the main listing of all programs on the Palm emulator, I get an
error message telling me that memory is being accessed that is deleted. If
I don't try to free the array memory, I get a memory leak. I'm not entirely
sure why this is happening. Method works with exit to another form within
program, but doesn't if user exits program entirely.

in the call to the function, passing it by variable. If I pass a constant
number corresponding to the number of records (say 2), instead of a named
variable, FreeStrings seems to work. (At least I don't get the memory
access errors.) Is there some way to fix this? I am showing six strings in
the list, but the possible number is greater. Am I missing some aspect of
how this string array and list object work?
