Hi Everyone,

 

I am new to the mono project and am trying to get it working for my current project.  I have been able to write a basic windows form application and that works well, but when I try to use an mdi form, it gets kind of funny on me.  I have included links to the screen shots for the difference, video so you can see the behavior, as well as the code. 

 

Basicly, the code is:

Form1 oForm = new Form1();

oForm.MdiParent = this;

oForm.BackColor = Color.White;

oForm.Show();

 

When I create a few child forms and then close the mdi form I get the following in the command prompt that I used to start the program:

 

Mono System.Windows.Forms Assembly [Revision: 54007; built: 2005/12/6 14:35:24]

Got a SIGSEGV while executing native code. This usually indicates

a fatal error in the mono runtime or one of the native libraries

used by your application.

Stacktrace:

This application has requested the Runtime to terminate it in an unusual way.

Please contact the application's support team for more information.

 

I don’t know if I am doing something wrong, or if there is something that I am missing, or if the implementation is incomplete and what I am seeing is a bug.  Any help or advise anyone can give me would be greatly appreciated.
