I also have problems running the demos, both in Win95 and in DOS 6.22.

Most of them most of the times exits with a stack trace consisting of

only one level backtrace. But sometimes some of them runs. This means

that if I start some of them 20 times in succession then in one try they

run without any errors, but most of the time they just quit with a

segmentation error.

I was able to compile them with DJGPP 2 without any problem, simply

running make.

I have tried the following combinations so far:

	Pentium 100 Mhz system, w. 40 Mbytes RAM, 2 GBytes Quantum IDE drive 	

(free space about 300 Mbytes), 

	2 Mbytes Trio64 video card

	- Under Win95 in a DOS window 

	- under plain DOS 6.22 with Himem only and with QEMM (but no qdpmi)

	A DX266 system with 16 Mbytes memory, 340 Mbytes HD, Trident 8900 CL
video 	 card

	- Under Win95 in a DOS window 

	- under plain DOS 6.22 with Himem only and with QEMM (but no qdpmi)

I found that the programs stop in 'allegro_init'.



Oh, I just see, that perhaps the problem is not with Allegro itself, but

with the 'palantir' event library of Dim Zegebart, as I have

incorporated it in allegro before the make. I will re-make Allegro again

without it, and come back with he results.
