Windows Vista"s revamped security features are posing difficulties for some IT security vendors looking to make their software work on the new operating system.
Although leading security vendors such as Symantec Corp., McAfee Inc. and Trend Micro Inc. have released updates or patches to make some or all of their products Vista-compatible, many others remain deeply entrenched in testing Vista versions of their tools.
Despite numerous complaints from gamers about poor performance on Vista, most applications written for Windows XP run on the new client OS out of the box, with only a few major exceptions, according to Brett Waldman, an analyst at Framingham, Mass.-based IDC.
