Sadly, there are bugs (!!) in LabVIEW, even if you are using the Spring (Service Pack 1) release. If LabVIEW crashes on you, it generally suggests you allow it to send an Error Report -- go ahead and do that, as (if nothing else) it alerts the Developers to on-going problems. In my (limited) experience, trying to track down the errors yourself is rarely productive -- most of the reported failures seem to be deep inside LabVIEW's "internals".
If you keep getting errors, and if you can figure out the "trigger" for the error, then it is not unreasonable to call NI's Support line and ask for help. If you can find a small piece of code that reliably causes the error, you can ship this off to the Applications Engineer (who can then bring it to the Developers and say "Here, Fix This!"). I've managed to find a few demonstrable "bugs", some of which were fixed in the subsequent Release ...
