Scrivener works great on Slackware Linux 13.37. I am using the 64 bit version of Slackware, but once I enabled the 32 bit multilibs, Scrivener just worked without any issues. Thanks for the 1.1 beta – and please keep the betas coming! I own a license for Scrivener on Mac and Windows but actually prefer to use Linux. I hope a new version will come after the current beta expires on July 31.
Yay. 
Yet another Slackware person!
How did you do that?
