- CLIENT/MGR/TRAY: When installed on Vista and UAC is turned on the user by default cannot create globally shared objects. This becomes a problem when protected application mode is turned off for keyboard and mouse detection. Basically all of the components would start up and fail to create the shared memory segment and report the error through stderr which most people don't look at by default.
The client is now the only component that is allowed to create the shared memory segment, if creating the global segment fails it'll create a local one instead. Both the tray and manager now just attach to the existing segment, first trying the global one then the local one.
