I have installed the new 64-bit version of SAS but it keeps blanking the right click context menu of programs/files. The context menu items return if I run the mouse cursor up it. After the first time it happened I uninstalled,cleared the registry and downloaded/installed a fresh copy and all was OK for a while but it has returned again. If I uninstall SAS all is OK so I presume SAS is at fault. Anyone any answers ? Sony Vaio laptop running windows & 64-bit. Ian
