Unfortunately, I'm running out of ideas. Since this sequence didn't work either, I think it can't be an issue with automatic termination...

I'm not sure what might be different on this machine.

The preferences should be saved in this file:

~/Library/Containers/com.textasticapp.textastic-mac/Data/Library/Preferences/com.textasticapp.textastic-mac.plist

Does this file exist?

I have an idea what might cause the problem. I added support for automatic termination and sudden termination in the latest update and this might be responsible for it.

Which version of OS X are you running and what kind of machine is this?

Can you please try that:

- open a new untitled document with Cmd-N

- change some preferences

- quit the app with Cmd-Q while the document is still open

- reopen the app

- open preferences

Did it save the preferences?

Hrmm, that seems to be caused by the open panel. It shouldn't cause a problem with the app preferences.

Did you already try a restart of the machine? Maybe a service isn't working properly.

It also can't hurt to try to repair permissions in Disk Utility. Maybe a permission is wrong so it's not possible to write to a file.

I have to admit that those suggestions are just a shot in the dark :(

Is there something logged in the "Console" app when you run Textastic?

Another user just reported this problem when the code completion list is showing:

"When you have a code suggestion show with examples of what to write and you haven't hit enter or dismissed the suggestions, and then change application, the window disappears and only reappears when you change back to Textastic."

I'll try to fix this in an update.

I've recently had a another customer with a similar problem.

In his case it helped to do this:

- Quit Textastic

- Delete the following folder: ~/Library/Containers/com.textasticapp.textastic-mac

- Restart Textastic

I'm not sure what's causing these problems. Did you have the Trial version installed before downloading the app from the App Store?

There seems to be a Fountain package for Sublime Text. The Fountain.tmlanguage at https://github.com/poritsky/fountain-sublime-text/blob/master/Fountain.tmlanguage should probably work in Textastic with slight modifications if it was re-packaged as a proper TextMate bundle.

Can you maybe tell me step-by-step what I have to do to reproduce the issue?

I don't see such a behavior on my machines.
