Try getting the very latest download from my site. There was a version available for a short time that was quite a bit slower at loading, but I think it's fixed now.
I'm not sure what happened there. Could be low batteries and a complete coincidence? I've just used YAFL to launch YAFL to launch YAFL (repeat for a while) but can't reproduce the problem. Anyway, I'm sure it's not something people would want to do often so I'm not too bothered
