Thanks Willam's feedback.
About contribute rights, is that mean enable version control? Or current user need the right?

I tried your solution, but problem still here, never leave:-(
BTW, does the problem may be caused by SP's working environment? I mean I installed the SP2010 on Win7x64 that not the official recommanded OS.
I tried use TFS2010 to control version, it works well, but need install VS2010 on each contributor's PC, that's a trouble.
Thanks,

Contribute rights means that the user must have rights to add and change items in the library. If you enable version control for the library, the user will automatically have rights to check out and check in.
I’m not sure what’s at play here. If SharePoint works well for everything else I highly doubt that the installation environment is the issue. As long as all SP’s services run and you use the correct ISS version. I’ll ask around if anyone else knows about what might be causing this.
Installing VS may be pain, but you only have to do it once. Personally, I like TFS because you better control and more options in TFS. (Such as associating check ins with change sets.)
Greet,
