Here's the output I see now (no more errors) Code: my-macbook-pro:wine-1.1.33 frankgrimes$ DYLD_FALLBACK_LIBRARY_PATH="/usr/X11/lib:/usr/lib" ./wine /Users/frankgrimes/.wine/drive_c/Program\ Files/Pylotro/pylotro.exe fixme:advapi:SetEntriesInAclA 1 0x33f81c 0x0 0x33f864 fixme:advapi:SetSecurityInfo stub fixme:dpnhpast:DllRegisterServer :stub fixme:system:SetProcessDPIAware stub! fixme:dwmapi:DwmIsCompositionEnabled 0x33e8d4 fixme:iphlpapi:NotifyAddrChange (Handle 0xf0f518, overlapped 0xf0f520): stub fixme:iphlpapi:GetAdaptersAddresses no support for IPv6 addresses fixme:win:FlashWindowEx 0x32d180 fixme:font:ExtTextOutW flags ETO_NUMERICSLOCAL | ETO_NUMERICSLATIN | ETO_PDY unimplemented fixme:winsock:WSAIoctl unsupported WS_IOCTL cmd (9800000c) fixme:imm:ImmReleaseContext (0x20026, 0x1d5c98): stub fixme:imm:NotifyIME IMC_SETCANDIDATEPOS fixme:toolhelp:CreateToolhelp32Snapshot Unimplemented: heap list snapshot fixme:toolhelp:Heap32ListFirst : stub fixme:imm:NotifyIME IMC_SETCANDIDATEPOS fixme:win:FlashWindowEx 0x327fd0 fixme:win:FlashWindowEx 0x3262f0 my-macbook-pro:wine-1.1.33 frankgrimes$ Any ideas where I can look to find out what's actually going wrong now? Are there logs to check, or do I simply need to enable trace output? Thanks, Frank Grimes
