I'm writing at program in Visual Studio 2012 (VB). It works fine. But I have one issue and i'm aware that there might not be anyone here that can help me, but i'll give it a try :-)
When I convert a psd-file using the com-object it's convertet fine, but the file is not released by vshost32.exe. All other file types I have tried are released at once and I have move them from my program, but not PSD-files.
This sounds like a bug. Are you able to provide the PSD file which caused the problem? If so, please open a bug report in the GraphicsMagick bug tracker on SourceForge and attach the PSD file to it.
