GridSplitter移動速度很慢

我有這個問題：實例化這個窗口後，打開右側的所有嵌套擴展器。（其中有7個）。最後一個包含一些元素。（TextBoxes）嘗試拖動GridSplitter。一切都很好，它工作流利。但！只要我點擊一個文本框（不管是哪一個），拖動變得瘋狂緩慢（鼠標放置後有時3秒+）。點擊進入這些調試消息出現在輸出文本框後：GridSplitter移動速度很慢

在此之後，瘋狂的拖動緩慢發生。在調試窗口停了下來，打算下一步顯示這些消息時：

嗯，我剛剛嘗試了所有可能的配置，調試/發佈模式下的x86，x64和任何CPU。不是一個變化。隨着每個控件添加到塊所有那些文本框它是慢（3嵌套滾動視圖〜每個拖動25秒） – 2012-03-29 13:58:04

我已經嘗試過在其他機器上安裝了相同的操作系統和.NET版本/補丁，它真的流利地運行！什麼是我的.NET安裝（所有機器都從同一圖像恢復） – 2012-03-29 14:07:00

以及..我真的不能重新安裝安裝。它顯然是贏得7的核心組件.. – 2012-03-30 05:34:51
