Hey guys,
So every so often (twice in the past calendar year), I see an unhandled exception pop up in my application, but for the life of me, I can't hunt it down to fix it or at least catch it. The issue I'm having chasing it down is that when I get the stack trace (I email it to my development group when the unhandled exception crashes the app on any users PC) the stack trace doesn't give me a method where it occurs...wondering if it's a bug. Something of note before anyone comments on that - I don't have a parameter anywhere in my application named oldIndex. The following is the exception and stack trace...any help would be greatly appreciated.
Specified argument was out of the range of valid values. Parameter name: oldIndex

If at first you don't succeed, skydiving is definitely not for you!
