Windows XP right click gobbles up CPU time
A MESSAGE on the Neohapsis bulletin board said that using Windows Explorer and right clicking on a file gobbles up the CPU to the tune of 100%. Mark Luczkowski says the problem only happens when you select files with a right click of the mouse, not having selected the file with a left click first. He says that the problem can be reproduced on both Pentium III and Pentium 4 machines. The folks over at the Inquirer were able to reproduced. Further, Mark has contacted Microsoft, which has told him that it won’t fix the problem because it will cause too many changes to critical code paths. The workaround, apparently, is to left click on the file first before right clicking it. But as the discoverer points out here, that makes the Single Click option in Windows Explorer pretty much redundant.
