New Vista computer. Installed SolidWorks 2008 SP4. Dellsupplied McAfee Internet Security. SolidWorks worked fine. We areNortons fans so uninstalled McAfee and installed NIS 08 & NSWB08. Now the "rotates the model view" by pressing and holding themouse wheel won't work in SolidWorks. Has anyone else experiencedthis? Symantec said that there should be no conflict between theirproduct and SolidWorks. If no-one can help then I'll have toabandon Nortons and run with McAfee. I am using a Logitech wirelesskeyboard and mouse with up-to-date software.SolidworksEdrawings
