I have Novell Client 2 SP2 (IR4a) for Windows 7 64bit with File Caching set to off, but when I cancel copying to NSS volume or cancel deleting form NSS volume, sometimes Explorer crashes (freezes) or PC reboots. The issue is seen on every PC with Windows 7 typically, when I copy or delete folder with a lot of files. Same issue with any client 2 SP 2 (any IR). Workstations with XP SP3 work fine. The server is NW 6.5 SP8 with latest patches. Any idea?
