I'm about a week into using Arch Linux and loving it, but every now and then I run into a random problem. Last nights was getting Dropbox to connect.
According to the ArchWiki, on the first run of dropbox after installing it from the AUR it should provide a pop up to get your configuration choices, and sign into your account. For me however, it simply loaded the icon and hang at "Connecting..."
The ArchWiki even has a section about this problem, which is completely wrong and wont fix the issue. Deep in the comments section in the AUR was a working solution.
