------- Additional comments from [EMAIL PROTECTED] Fri Aug 15 12:50:31 +0000 2008 ------- This is because some COM object instances (f.e. desktop namespace root obtained by SHGetDesktopObject()) are held as a singleton by COM. Though these ojects can only be used directly from the thread that instantiated them first because the implementation of these objects is not guaranteed to be thread aware. This is reflected by the (undocumented fact) that most of shell or UI related Windows API function can only be called from a STA. Marshalling between apartments is done by a SendMessage call to the threads message queque that instatiated the COM object. Threads that instantiate COM objects must at least have one Window with a Windowproc so that the Sendmessage mechanism works. This thread must never be blocked. A fix can be done in SAL with MsgWaitForMultipleObject if only SendMessage calls are processed while waiting for a synchronization object. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
