Hi guys,
Just an observation from a windows programmer (amateur) its not wise to
close a window if a "close/exit" option is given particularly in an Object
Oriented environment. shutting a program down without destroying the
objectrs that have been created can cause all sorts of memory problems.
in the programs I write I always have a routine associated with the
"menu-file-exit" action that goes through each class of object used and
destroys each instance of every class used.
Cheers
Dene

Say.. I tried 7 times, and got it 7 times. I tried both while fgfs is
loading
or after the load is completed (and ready to play).

Eheh, good reason to avoid crashing it :-).

Yep, a Dell laptop running FC3 and the latest ATI fglrx drivers.

Is there an easy way to build fgfs w/ debug option (I must admit that
I didn't look at it yet, but I will, soon), such as ./configure
--enable-debug? So that I report bull bt?
