Actual error dialog

Description of Problem:
If after you stop on a break point in the debugger, you hit "stop" in Visual
Studio, an error occurs.

The error message says:
"Unable to stop debugging. Operation not supported. Unknown Error: 0x800400c3"

No error message is output in the linux terminal where monovs-gui-server is

This leaves Visual Studio in an unstable state, and it also leaves the
debugging process running on the Mono side.

This was found in MonoVS 0.3p3.

Steps to reproduce the problem:
1. Create a new solution in VS based on the C# winforms template project.
2. double click on the new form
3. in Form1_Load, add the line:
4. Add a breakpoint on the Console.WriteLine() line.
5. Click "Mono / Debug remotely in mono"
6. Notice that the debugger correctly stopped on the break point.
7. Press "stop" in Visual Studio
8. Notice the error as above.

Actual Results:
I get an error message in Visual Studio.

Expected Results:
No error message and the debugger process on linux should stop.

How often does this happen? 
every time I've tried it.
