OK, so maybe i'm just dense, but I can download an app from the market, but it wont show up in extras. I need to launch it from the market. Is this normal?
I am having this exact same problem. When I click on the write button along the top, it goes for about 3 seconds, then stops. Frustrating.
Edit: try running as adminstrator. Seems to be working for me now. Thanks for the tip above.
