How can I resume a process after calling DebugActiveProcess?

Question

I am using this DebugActiveProcess to debug an already running process.

http://msdn.microsoft.com/en-us/library/ms233510.aspx

Right after calling the method, the debugee is suspended. How can I resume it ? I tried ICorDebugProcess.Continue, no effect. I also tried the managed debugger sample (mdbg). Same behavior: "at" suspends the process, "re" does not seem resume.

Is this a bug in the platform or is there a way to resume?
