Hi Mike,

Plugin engineers found out:

We have tested these files on windows and Solaris Sparc. These files also can not 
been opened successfully on our side. StarOffice and Mozilla will hang up. After 
debugging and testing, we found the this problem will happens when a document 
contains OLE object.  Any document(*.sxw, *.sxc,*.sxi) including some OLE 
objects  will hang up StarOffice. This can be proved by delete all OLE objects in 
file CWS-Introduction.sxi, then it can be loaded again. And if you add a OLE 
object to a normal file( that can be loaded), it will not be loaded again. This 
happens also on Solaris.

From debug, we also found where StarOffice is hanged up, it is
->after load document, call statusBarManager::UpdateControllers
->StatusbarController::update()
->StatusbarController::bindListener()
->SfxOfficeDispatch::addStatusListener
->SfxDispatchController_Impl::addStatusListener()
->SfxDispatcher::QueryState
->SfxShell::GetSlotState()
->SfxStubSfxObjectShellGetState_Impl()
->SfxObjectShell::GetState_Impl()
->SfxObjectShell::IsModified()
uno::Reference < embed::XEmbeddedObject > xObj = 
GetEmbeddedObjectContainer().GetEmbeddedObject( aNames[n] );
->EmbeddedObjectContainer::GetEmbeddedObject()
->OCommonEmbeddedObject::getCurrentState()
StarOffice is hanged when call ::osl::MutexGuard aGuard( m_aMutex );
The m_aMutex is not realsed here, so  StarOffice stopped here.
This may because some exception in OCommonEmbeddedObject::changeState.

Please contact me if you need testdocuments.
Or create and load a described document with the mozilla plugin.
