Hi all,
Thanks for the response,
You said it right : "reset" = bad for user
So what else can we do ??
if we just close the forms and exit the application will it not
cause memory leak ?
is it wise to put an if/else aroud EVERY MemPtrNew/MemHandleNew/etc..
that we do ?

maybe in the first days - but surely, "reset" = bad for user.
i moved away from the ErrFatalDisplay... routines to give the
user the re-assurance that everything will be a-ok and bring
up a custom dialog of my own.

you can check out how i do this in the Cube3D sources - which you can
get here. i create a custom form called xmemForm.

i believe this issue should be mentioned somewhere in the design
guidelines.. ErrFatalDisplay.. routines are great for debugging :)
