There were some attempts to debug (see above and below)

It's definitely not fault of DOS and not everything coming from "Windows" is good at all. Finally, HDPMI has a very good fault handler ... unfortunately there is no good way to run VGAP386 on it

This is definitely NOT true. It might fit for your special case (because VGAP386 is more buggy than NEO) and you had luck with your XMS&EMS, but generally DPMI32 is more stable than XMS, even even than EMS. EMS is crap (except 8086's EMS via additional memory cards, maybe)

That DOS/32A has a feature to "switch to text mode on crash" and this could be used to debug this problem

Thanks, but did you test it ? It's unusably buggy

At least, topic starter (from "old" forum) is happy with NEOPAINT now
