I have just started developing Mac OS X applications in Oxygene for  
Visual Studio and have come against a peculiar problem.

Steps to reproduce :

Create a new Oxygene Cocoa for OS X Leopard application.

Switch to Interface Builder and add a TextField and a Button to the  
form.

Save and switch back to Oxygene.

Select designable.nib and run the Custom Tool by right-clicking and  
selecting menu item.

Build project.

Execute project from Finder.

Click in TextField and press an arrow key.

Expected : nothing or selection moves in text.

Actual : Exception that closes application with the following Console  
output :
