c# Office interop class

I have an office interop class that I need fixed. You must have visual studio 2010 and office 2007, 2010. This project has a few bugs in the word interop. It crashes visual studio when using office 2010 and 2007. Using office 2007 there is something with file locking. Office 2010 the bug is getting it to run without crashing. Office 2007 the bug is that you can send one image but trying to send another image it sends the first image over again. It will never send the second image. The project allows you to load two different images and send them both. The goal is to get it to work with XP and forward and Office 2003, 2007, 2010. Thanks and good luck
