I scanned the entire hard disk and found only one copy of go32.exe in 
c:\djgpp\bin. My first post had the actual screen dumps of the error 
messages. I will include it in here just in case.

The machine information:
processor: AMD 386sx/sxl 20
200 Mb hard disk
2 Mb Ram
ega card with monochrome monitor

Both bios shadow and video shadow has been disabled.


The screen dumps are shown after the command which produced the output.
