BTW, perhaps we wouldn't be hitting the maps as hard if you didn't time out the maps in an incredibly short period of time.
Here's an example. I opened a map to plot out where I want to go cache. It took two minutes to load. It finally loaded. I zoomed in and out and panned over along the way to an area in which I had few finds. I zoomed in, and... all my finds disappeared? Huh? I zoomed out - find icons were there. I zoomed in, and they disappeared. Zoom out, they're there; zoom in, they're gone. So what do I have to do? Hit refresh on the browser. Re-center where I wanted to look. Zoom in. Oh, there the icons are again.
Wait about 5-10 minutes and then repeat.
