I have ESS 3.0.667.0 and XPpro with SP3. Over the past week, I've been getting a messagebox with "Eset Service has encountered a problem and needs to close. We are sorry etc etc" The error information is szApp: ekrn.exe ModName: mswsock.dll ModVer 5.1.2600.5512 offset:0x0001b2c2 When I click close, I lose internet access for a minute or so, and then I assume the service must restart. The error does show up in EventViewer, so I'm not sure if SP3 has changed mswinsock.dll or if there is some corruption either with ESS or mswinsock. Anyone else having this problem, and is ESS actually still working properly? Task Manager reckons so, but........ Colin Perhaps should add I'm using Safari for Windows as my browser.
