Glass not rendering correctly

[Rob Cherryman]

I just created an office environment and in preview modes it looks great, angles are good, window tint is appropriate, then once I do a hi-res render it seems like the window is giving off multiple reflections even though I turned them all off.  This is baffling and I'm pretty stuck.  My screen grabs come out fine, and I need to finalize 7 renders for my client.

Any suggestions?

What type of glass are you using? Make sure to use the non-refracting type, as I think that might be the issue.
