Thank you. that was obviously more like a build. To confirm what i was doing I also did: ./wine --version and found that I was in version 0.9.53 for the test. So was I right with the following? Code: colin@colin-laptop:~/wine-git$ ./wine "C:\Program Files\FastStone Capture\FSCapture.exe" preloader: Warning: failed to reserve range 00000000-60000000 preloader: Warning: failed to reserve range 00000000-60000000 err:dosmem:setup_dos_mem Cannot use first megabyte for DOS address space, please report preloader: Warning: failed to reserve range 00000000-60000000 err:dosmem:setup_dos_mem Cannot use first megabyte for DOS address space, please report err:dosmem:setup_dos_mem Cannot use first megabyte for DOS address space, please report preloader: Warning: failed to reserve range 00000000-60000000 err:dosmem:setup_dos_mem Cannot use first megabyte for DOS address space, please report fixme:systray:handle_incoming unhandled tray message: 4 fixme:keyboard:RegisterHotKey (0x10032,73,0x00000000,113): stub fixme:keyboard:UnregisterHotKey (0x10032,73): stub fixme:msvideo:DrawDibRealize (0x1, 0x30c, 0), stub fixme:systray:modify_icon balloon tip title L"", message L"" fixme:systray:modify_icon balloon tip title L"FastStone Capture is Minimized.", message L"To show the Capture Panel again, click on this icon.\rTo terminate the program, right click on this icon and select \"Exit\"." fixme:msvideo:DrawDibRealize (0x6, 0x30c, 0), stub As I suspected, it is not a regression, as if I did it right this time the application still behaves the same 0.9.53 as 1.0rc3.
