taotao,
Clean the workspace: CCSv4 stores various information in a folder called '.metadata' located in the user's workspace. The contents of this folder can get corrupted over time, causing various instability and strange behavior. Cleaning the workspace often helps resolve these issues. The simplest way to do this is to delete the '.metadata' folder in the workspace. This will essentially reset the workspace and restore the environment to the default behavior. All projects that were in the workspace will need to be re-imported into CCSv4, even though they are still physically in the workspace folder. Also note that any modified preference settings will be lost (set back to the default setting).
If you wish to avoid resetting those preferences, export the preferences to a file (outside the workspace) by selecting 'File->Export…->General->Preferences->To preference file' before deleting the workspace. Once the workspace has been cleaned, those preferences can be imported back into CCSv4 by selecting 'File->Import…->General->Preferences->From preference file'
如果你打开的graph窗口较多的话，有可能出现调试界面速度变慢的问题，如果CCS调试速度没有影响，那么请关闭CCS尝试将workspace 下面路径下的所有内容删除，然后打开CCS，重新添加变量到Graph窗口试一下
C:\workspace\.metadata\.plugins\com.ti.dvt.graph.visualization\savedSolutions
