Visio Shape Glow effect printing

[gunslingor]

I have implemented the shape glow effect described here: http://blogs.msdn.com/b/saveenr/archive/2008/02/15/visio-trick-one-color-and-two-color-glows.aspx?CommentPosted=true

And it looks and works perfectly, except when it's printed. When it's printed it looks to me like the shape in front of the glow as well as the glow itself do not show the alpha channel. Any ideas how to fix it? It prints fine when I save as jpg, but not when printed as a VSD or pdf and I really don't want to have to save multiple versions anyway.

Thanks
