Yes, I know these DSK-file crashes, but this is something else. Anyway, I deleted the file fp.dsk - SIGSEGV. I deleted the remaining files - SIGSEGV.
Always helps run old fp.exe 0.9.2 18.05.2004 from 1.0.11 before run fp.exe from 2.6.2. Both versions use CWSDPMI v7. I still think that fp.exe will something set in the memory and after completion of the program does not reset this. Of course this is only my assumption. When I have the source program hopefully learn more. Anyway thanks for the help.
