求助：VS2008调试时不能编辑.aspx.cs文件
在VS2005中可以在调试Web工程时，对.aspx.cs文件进行编辑，但在VS2008中编辑不了，有以下提示：
Changes are not allowed while one is running or if the option 'Break all processes when one process breaks' is disabled. The option can be enabled in Tools,Options,Debugging.
但我已在Tools->Options->Debugging中选中了'Break all processes when one process breaks'
并且在Tools->Options->Debugging->Edit and Continue中选中了'Enable Edit and Continue'
VS2008的选项（除了新增的）与VS2005中的选项都选择一致，还是不能在调试时编辑，特请教。
