Hello, Downloaded and installed Wine to run an old DOS program (database gui for Clipper5 called dbu.exe). The layout of Wine is well thought out. Anyway, the problem is the following that I just have a blank window. I ran the code (found that in the forum, thankyou) for old 16bit programs first: sudo sysctl -w vm.mmap_min_addr=0 This is the terminal readout: paul@paul-asus-laptop:~$ wine start 'c:\Program Files\dbu.exe' fixme:exec:SHELL_execute flags ignored: 0x00000500 paul@paul-asus-laptop:~$ fixme:int:DOSVM_Int10Handler Get Font Information - Not Supported fixme:int:DOSVM_Int10Handler Set Background/Border Color: 0/1 Any help greatly appreciated! Kind regards
