Subject: Retry: Problem with go32 and 386max memory manager

My first attempt to report this failed rather miserably - sorry.
I wanted to report a problem I first suspected was from my memory manager but
I suspect it is a go32 problem now.  I recently got the go32 1.11main1 version
and the 2.57gcc binaries to build programs.  The compiler/linker works fine
and I can run programs that put the screen in graphics mode (vga and tseng4kn)
but when I try to use a line (or any other kind of graphics drawing tool)
I get a "general protetion fault at eip=151e" .  I get this with the djtst111
files and with my test program below.
Now I hear that QEMM has an auto/on feature that has to be turned on all the
time and I suppose 386max has this "feature" too but I think the 1.11main1
is the cause because if I run the program with the go32 1.09 version I get
no problems.
  I am using 386max version 7.0 on a Hauppauge4860 25Mhz motherboard with 
14Megs ram and a Hercules Dynamite Pro 1Meg graphics card. If there is any
other information you need please feel free to ask.

ps: I think the delay(x) function is not counting milliseconds correctly. It
seems to count in 1/2 millisecond per one x.
