I'll post now a simplified example, just to make it clearer so to 
trigger the cat.c32 issue only (#4 above), but you should be able to 
test with it more cases too.

   *** SYSLINUX.CFG START ***
DEFAULT cat2
PROMPT 0
F2 help2.txt
LABEL cat2
COM32 cat.c32
APPEND help2.txt
   *** SYSLINUX.CFG END ***

   *** HELP2.TXT START ***
LINE 1 OF HELP2.TXT
   *** HELP2.TXT END ***

Note that "help2.txt" is "less-than-one-line" only. There is no final 
[ENTER] in "help2.txt" either.


In particular, I used syslinux.exe, and I just repeated the test with 
5.00pre12 with the same result.

When booting, are you able to see "LINE 1 OF HELP2.TXT"?

When manually running that "cat2" label from the boot prompt, are you 
able to see "LINE 1 OF HELP2.TXT"?

When pressing "F2", are you able to see "LINE 1 OF HELP2.TXT"?

For these 3 questions, my answer would be "no, I can't see the text 
on the screen; the new boot prompt covers the resulting displayed 
line each time anew".

So I have at least 3 different situations here that are triggering an 
unexpected (or at least unwanted) behavior.

Evidently if you want to know if the problem is at the first or at 
the last line, simply add more lines to "help2.txt" and repeat the 
tests. (Note that the problem I reported about DISPLAY files is 
different than this case.)

Hopefully you can reproduce them now.

TIA,
Ady.
