Hy Toro, thanx for repling.

Actually, my program has a check wheter envelope is present or not. I know that, because i dumped the progi with some option, that envelope stayed in the file (even the file became bigger for aprox. 400 kbite) and i could run the program. The next time i dumped with classic option (paid said not packed) and program crashed (the reason of this whole thread).

How can i find the code where the progi check if envelope is present or not?
I tried also to change any bite in the orignial program. Result is the same, crashing.
Thanx,
Regards, MAHMUT
