[Mono-osx] Problems with Oxygene and CocoaSharp

[Miguel de Icaza]

Hello,

    It seems like you have an older version of Cocoa# than Oxygene
expects.

> 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
