Just installed the app.
Opened it the first time, no problem.
Accidentally closed it, so I restarted the application.. only this time, the screen appeared on the top left, showing only white parts.. The toolbar, etc, are not visible, so I could not move it. So I killed the program, and restarted again.. This time the screen has moved even further up the top left screen, only a little white box (of the bottom right screen) is visible.
What do I do?
Trello tries to remember its last window position when you close the app, so it sounds like something might not be working quite right there.
I would suggest completely uninstalling the app from your computer and then redownloading it from the Store and see if that solves this: http://help.trello.com/article/1107-how-to-uninstall-the-trello-desktop-app
