I've try to use Lightbox Plus image editor (http://www.lightboxeditor.com/) under wine. It start's, but always freeze after few minutes. It says: Code: err:ntdll:RtlpWaitForCriticalSection section 0x7e4518a0 "x11drv_main.c:X11DRV_CritSection" wait timed out in thread 0009, blocked by 0018, retrying (60 sec) After a minute says the following message: Code: wine: Critical section 7e4518a0 wait failed at address 0x7bc3be30 (thread 0009), starting debugger... Unhandled exception: wait failed on critical section 0x7e4518a0 thread_data_tls_index+0x3c err:seh:raise_exception Unhandled exception code c0000194 flags 0 addr 0x7bc3be30 This is a bug and I need to report it, or I've made a mistake? Or is there any solution for this type of error?
