Vista SP1 still hates DPMI > 32 MB (Miscellaneous)

Actually, now (after rebooting) it doesn't even seem to run any DPMI apps if HXNTVDM is loaded first. It just silently does nothing (although HXNTVDM unloads itself). So that's no help. (BTW, it's dated Jan 5th. Is there a newer version?)

But yes, DPMI.EXE from HXRT.ZIP does say "largest free/lockable memory block (kB): 32768/11652 before loading the TSR and 529148/529148 afterwards. (But it still doesn't seem to work with other programs.)

Neither of you use Vista on a regular basis, right? (You both use XP, last I heard.) Well, for Vista Home Premium SP1 for me, it doesn't seem to work for my personal compiles of PAQ8o8z (DJGPP or Causeway). I don't know why, so I'm (of course) inclined to say, "You haven't tested enough" because I own Vista and you don't and it still doesn't work. But hey, if I'm doing it wrong, oops. However, so far I haven't gotten any results. :-/

EDIT: By the way, GO32-V2.EXE from DJGPP 2.04 beta says (and has always falsely said) "DPMI memory available: 493918 Kb", so it's not just reporting the memory that is wrong, it's actually trying to use it that doesn't work.
