[boost] [interprocess] Different processes accessing shared memory in different locations

Hi Our application has the following scenario using Boost V1.0.52: 1) Process A writes to boost interprocess shared memory. The files appear at C:\ProgramData\boost_interprocess\... 2) Process A launches Process B 3) Process B attempts to read from shared memory but fails. It is attempting to read from: C:\Users\<username>\AppData\Local\Temp\boost_interprocess\... This failure only occurs on one single Windows 8 64 bit machine out of many we have tested. On all other machines, the application works perfectly. Please could somebody advise: What changes to our application could be made to avoid this? What changes to the machine's configuration (eg. Registry) could be made to avoid this issue? Many thanks Thomas Sanham
