Using forms in C++/CLI AutoCad plugin

I'm having a problem displaying a custom windows form in my C++/CLI AutoCad 2014 plugin. 


The code is posted below. The application does nothing AutoCad specific, it only opens a windows form I've created. 


What happens when I call this command is that if I let the form display on screen for some time, AutoCad will crash, usually within 1-2 minutes after the form has opened. 


Is there any known problems calling a Windows Form from a C++/CLI AutoCad plugin?


static void TestGUI()
MyForm ^myForm = gcnew TestProj::MyForm();

can't see anything wrong with your code, so we need to see a small rebuildable sample applications which shows the same problem to be able to help

It seems the problem did not occur by opening the Windows Form I had created. However, AutoCAD crashes as mentioned in my original post when calling the standard Windows::Forms::smileysurprised:penFileDialog from within my custom form. 


After I discovered this, I replaced the standard Windows::Forms::smileysurprised:penFileDialog with Autodesk::AutoCAD::Windows::smileysurprised:penFileDialog, and this seems to have solved the problem. I have not experienced any AutoCAD crashes after this change.
