Now I have read in some note, that the protected mode wrapper that is obtained via _go32_dpmi_alloc_iret_wrapper (or so) or via _go32_chain_protected_mode_interrupt_vector (or so) is not locked by djgpp. Since it is essential to lock all code and data accessed during interrupt time, I wonder if I risk a trap in my app. Has this been fixed/changed in the newest release, maybe ? If not, what is the workaround ? Lars
