I once had a similar issue with a Silverlight program I wrote. In my case I ended up adding worker threads to handle data processing with an event to signal when it was done processing and followed up that tweak by consolidating my SOAP requests as much as I could (ironically making it even faster helped fix it). Timing issues can be rather tricky sometimes but the upshot is that if your going to have a problem, running too quickly isn't a bad one to have to deal with.
