當我關閉文檔時，我看到有如此奇怪的行爲，DockPanelSuite。當我單擊文檔右上角的關閉'X'時，頂部文檔按預期方式關閉(calls FormClosing event and Dispose() method of my derived DockContent class)，但文檔中仍有一個小選項卡。它就像DockContent認識到內容應該被丟棄並且拋棄所有的內部控件並且Form.Text從標籤中消失，剩下的是一個沒有任何文本的小標籤。關閉DockContent文檔後出現DisposedObjectException
進一步嘗試再次關閉選項卡或點擊選項卡導致'ObjectDisposedException'.
這裏是我的環境規格：
Visual Studio 2008
DockPanelSuite AssemblyVersion("2.5.0.*")
Windows 7 x64
下面是一個堆棧跟蹤。步入代碼，我可以看到它彈了當它試圖獲得IDragSource.DragControl這是我佈置完畢控制的實例提前幫助

感謝。
除了這個小小的打嗝，我對圖書館非常滿意。
