Perhaps it's a version issue. I am running it from Try F# - tutorials, which seems to be a couple of builds old for some reason:

I believe that the build number there is Silverlight-specific. Having said that, the problem you're seeing is limited to displaying bigints - you can actually still use them in calculations without any other issues. For instance, try this:

do
    let x = 17I
    let y = 23I
    let b = x < y
    printfn "%A<%A: %b" x y b

Yes, the build is specific to Try F# and it is an issue with formatting. Thanks for reporting it.
