Re: [Ikvm-developers] IKVM can not cast sun.awt.image.ToolkitImage to java.awt-image.BufferedImage

[Volker B. <vol...@go...>]

Hi Vito,

I have fix 2 bugs in IKVM. A snapshot can you find at 
http://www.file-upload.net/download-4084654/IKVM.zip.html or build it 
from repository. Please test it. With my very short test it has work.
