Actually, I was able to change the text in the MS-DOS stub of a bound
Windows executable and it ran without complaints (in both DOS mode and
Windows).  I changed the text from "this is a Windows NT windowed
executable" to the more familiar "This program cannot be run in DOS
mode. ".  I did this without updating the CRC checksum value that is part
of the PE header (but I'm not sure if the CRC includes the MS-DOS stub).  I
still haven't tried anything that changes the length of the executable...
Perhaps Rob will pipe in and settle this issue.
