Hi,<br><br>I'm using version 1.41 in a Windows Server 2008 host.<br><br>If I run an application as a service (in fact launching it with srvany) that creates a named managed_windows_shared_memory and then execute a user application that tries to attach the shm, the later cannot succeed to attach - error is: "The system cannot find the file specified".<br> <br>On the other hand, if the shared memory is of type managed_shared_memory then all runs fine.<br><br>Couldn't this indicate that in the windows approach the file mapping object should be created with more global security and access rights?<br> <br>Thanks,<br><br>Rui<br>
