Needs FlWriter of its own config? (Users)

I normally and successful use programs of "xfdos" by Georg: Dillo,, MuPDF, flmail, flviewer etc, but I have serious problems with flwriter:
I use the standard config in FDOS: I tried with: jemmex, no ems, without noems parameters, and also starting with emm386; but in flwriter I can only write new files and export them in txt format.
All other attempts (open file, save etc. produce this result:

Any suggestions?

Yes, this can be a problem if you have set the LANG environment variable before. I forgot again to look into this.

However, I am afraid there could be further reasons for the crash. I could not reproduce the problem here though. Did you start with f.bat?

	Hi, sometime can be an invalid video resolution.. open f.bat after 1st row insert a new row like this @set nanoscr= 800 600 256 (or others resolution aivable from your video card) Roberto

Yes, the NANOSCR variable must be defined.
If is not then FLwriter ends with this crash report.

Just an idea, to not waste limited DOS environment space, maybe it could be good to add FLTK specific varables into DJGPP.ENV and read it from there like other DJGPP tools do. Then you have only one env var. e.g. SET DJGPP=C:/DJGPP/DJGPP.ENV
Also the program could have some hardcoded defaults to not crash if var not present or rather print an error explaining what need to be set.

Thanks for your interest.
I tried flwriter on 4 different PC, with or without
"set lang", and with and without "set nanoscr...", but problem remains.
(Normally, for me, the gui of deskapps also appears fine with 1024x768x16k.)
I add, however, that typing: flwriter ... * .htm, the file, if does not contain images, opens, and I can modify and save.
And opening a new text file, it also accepts the input image,
but when saving crash.
Flwriter instead works well, with each feature, on the same PC, but using it in win xp.
memory manager problems?
thanks
Andrea

If it works in Windows XP and not in DOS it is often a nullptr problem or long file name support. That has to be fixed in the code. Windows XP is forgiving nullptrs and continues.

Can you please try 1024x768x32k?

	It could also be my program, but I currently cannot reproduce it here. Sorry. > > Can you please try 1024x768x32k? > > > > Georg > > The screen is ok with 1024x768x32k but remain instability problems. I think > I will have to rebuild my freedos config... > > regards > andrea

What happens if you preload some different DPMI server?
Try to run HDPMI32 from HX-DOS package first. Does it help with stability?
