专家包占用CPU高，什么都不用的情况下CPU占用30％，环境Win2003 RAD Studio 2007。

卸载专家包，BDS占用CPU正常。

请问您的专家包是什么版本？如果有可能，烦请从此处下载最新的每日构建版试一试？

我的也是这种情况，启动后什么都不用cpu就在30左右，而且最小化后也是这样。反复卸载安装cnpack对比后确认。

我的没有你们所出现的问题，我觉得应该是别的应用程序引起的问题

楼上猜的不对，因为我重装过系统，在没安装别的任何软件的情况下都是这种状况。

  但是现在这个问题今天解决了。方法很简单：换了个本，高兴！

针对BDS下低配机器CPU占用率过高的问题进行了修改，请关注 577 版本的发布。
