I have only good news... The window list with ALT+0 works, good job, thank you. Yes, I am using the option -Cr just for debugging purpose.
>Did you try to use -O- to recompile all rtl/packages >to rule out optimization error? Not yet, because I found the cause of the freezing program FP.EXE when I use trace key F7 or run program with breakpoint(s). *The cause is CWSDPMI.EXE r7.* If I use an earlier version CWSDPMI.EXE r5 or another DPMI server (hdpmi32.exe) everything works as it should! Some users reported a bug to me (using new CWSDPMI r7) Page Fault cr2=00400000 at eip=419; flags=3206 Eax=00000300 ebx=00330021 ecx=000000a6 edx=bfeb00bf esi=00000000 edi=00000000 Ebp=00000001 esp=00003ffa cs=87 ds=bf es=b7 fs=0 gs=0 ss=a7 error=0006 The explanation on http://www.delorie.com/djgpp/v2faq/faq12_2.html: "This usually means the program tried to access some data via a NULL or an uninitialized pointer." But using CWSDPMI.EXE r5 or hdpmi32.exe no error occurs (with the same program). SUMMARY: Thank you very much, now I am happy because everything works including the possibility of debugging. I'll do more tests but I assume that everything will be fine.
