v4.0.3 on Win7 64b An easy one to reproduce: - Open Tor Browser - Head to the File menu (Alt-F) and select "Work Offline" - Close Tor Browser Windows shows a werfault pop-up announcing that "Tor Browser has stopped working" and providing a button to close the program. There is no visible indication as to why it crashes. This is what Process Explorer thinks the stack for the Tor Browser process looked like, while the werfault pop-up was waiting for me to kill the process ``` wow64cpu.dllTurboDispatchJumpAddressEnd+0x6c0 wow64cpu.dllTurboDispatchJumpAddressEnd+0x4a8 wow64.dllWow64SystemServiceEx+0x1ce wow64.dllWow64LdrpInitialize+0x42a ntdll.dllRtlUniform+0x6e6 ntdll.dllRtlCreateTagHeap+0xa7 ntdll.dllLdrInitializeThunk+0xe ntdll.dllZwWaitForSingleObject+0x15 kernel32.dllWaitForSingleObjectEx+0x43 kernel32.dllWaitForSingleObject+0x12 xul.dll!NS_InvokeByIndex+0x341b2 xul.dll!XRE_AddStaticComponent+0x7ac9 ``` **Trac**: **Username**: jah
