2.22b. Nope, I'm using the default size in both cases, on the same resolution monitor. Everything related to Fast Dial (including firefox) is identical. I can't confirm that's the case for both flash and java, and that's where I think the problem lies. I take it then that there isn't a cache where thumbnails are saved that i can just copy over?

haha No, they aren't blurry. They aren't loading completely when it takes a thumbnail on one computer.

Computer 1: Set up gmail.com as a fast dial tile. It loads the initial gmail page and makes a thumbnail of the "loading" bar along the top. NO matter how many times I hit refresh or what speed I set my internet connection in preferences, that's all I get.
Computer 2: Set up gmail.com as a fast dial tile. It loads the inbox and makes a thumbnail of the inbox. The fast dial thumbnail looks like gmail. Looks way better.

This similar thing happens to several of my tiles. ingdirect.com on one I get the orange bars at the top and bottom on computer 1, on computer 2 I get the orange bars, the blue menu down the right, and even a freeze-frame of the flash animation that takes up 60% of the page. I know it's not a bug with Fast Dial, it's a problem with my other software that I can't sort out. But I figured the easiest solution would be to copy over the files that have been saved on computer 2. I figure it must save them because it doesn't regenerate the thumbnails everytime, so they must be stored. I was unable to find them however.
