I can confirm this. Can't get wine to start any programs now. Using ubuntu 8.10 32Bit. Is there an easy way to downgrade to 1.1.11 ? 1.0 is in the repository but it's a bit too old. Starting winecfg from shell gives this output: Code: fixme:ntoskrnl:KeInitializeSpinLock stub: 0x462740 fixme:ntoskrnl:KeInitializeSpinLock stub: 0x46273c fixme:ntoskrnl:KeInitializeSpinLock stub: 0x462744 fixme:ntoskrnl:KeInitializeSpinLock stub: 0x462748 fixme:ntoskrnl:KeInitializeSpinLock stub: 0x46274c wine: Call from 0x7b8456d0 to unimplemented function ntoskrnl.exe.KeInitializeMutex, aborting wine: Unimplemented function ntoskrnl.exe.KeInitializeMutex called at address 0x7b8456d0 (thread 0015), starting debugger... wineserver crashed, please enable coredumps (ulimit -c unlimited) and restart.
