Yes, I've found that HandyNotes and TomTom like to take turns being the most ridiculously slow loader, sometimes up to 4+ seconds. I think the problem is actually Astrolabe, the map library those two both use, because of all the processing and querying it does immediately. It really needs a full rewrite, but I have way too many other things to do, and Astrolabe is basically made of spiders (big fat hairy ones) so I have no intention of doing it myself.
