推荐答案

我发现此刻重绘的控制占用了80％ CPU时间......

I have found that controls redraw at this moment takes up to 80% of CPU time...

除非我的计算机被大量的应用程序困扰，否则我从未有过这种情况。

我可能建议检查你的windows主题/风格设置？如果你的窗户上有很多控件，P4可能无法提供它。

I have never had that occurance unless my computer is super bogged down with a lot of applications.
Might I suggest checking your windows theme/style settings? The P4 might not be able to hand it if you have a LOT of controls on your windows.

这很奇怪，但只有很少的控件。最显着的效果是TextBoxes，ComboBoxes和GroupBoxes。

你的意思是哪一个？

It''s strange, but there are only few controls. The most noticable effect is for TextBoxes, ComboBoxes and GroupBoxes.
Which one setting do you mean?
