Everytime I update the TDS databases, PG nearly always informs that dcsmutex.exe has changed. The timestamp has changed so I assume it has been updated during the update of the databases. I just want to check that this is correct ? Another question I've got is that PG refers to dcsmutex.exe, but there only appears to be a dll file dcsmutex.dll. There is also a Pre-fetch file which refers to dcsmutex.exe. Is there really a dcsmutex.exe ? What's going on ?
