I have a new machine that I have been testing. When I use the appbrowser to download an extension that has a .dep file it will freeze when it gets to 90% of the first dep. If I try to download the same extension again only the extension is downloaded, not any of the deps. Downloading extensions with the CLI works correctly, all of the dependencies are resolved and installed. I did notice that the dependency that hangs at 90% actually downloads completely but does not install.
I have not seen this happen with any of my other machines, only this new one. It is an Atom N270 machine.
