I'm using the standard dialogs that are provided by the system. I don't think I can change that behavior.

So you just created a new untitled document and didn't even save or change the syntax definition when this happened?

Thanks a lot for taking the time to tell me your idea. It does sound interesting. This would make it truly a "wheel" similar to a rotary dial on old phones if I understand it correctly.

It would also fix the problem of linear swipe gestures which would eventually reach the border of the screen. Your suggestion would mean that the user could move the cursor indefinitely.

Here's a thing you could try, maybe the the sandbox profile is corrupt:

• quit Textastic
• delete the following directory: ~/Library/Containers/com.textasticapp.textastic-mac (this will delete all of Textastic's preferences, sandbox data and custom bundles/templates)
• restart Textastic and try again

For some unknown reason, the Mac OS X sandbox daemon denies Textastic to read the file. Did you use the open panel to open the file?

It does. Everything worked for me and I could not reproduce it as long as iCloud was enabled. But, as soon as I disabled iCloud, I saw the same problem as you did. It's a variant of the problem that I thought I had fixed in 1.1.

So there seem to be two workarounds:

1. change the syntax definition before saving the first time
   
2. enable iCloud

On all of my development machines, iCloud is enabled, so I didn't see this issue.

I'll try to fix this problem. Thanks a lot for your patience and for your help.

Could it be an encoding problem? Which text encoding do the files have?

Does the error have any additional details? Do you see something in the Console app (system log) when this happens?

Please create another screencast. I must be doing something different. It is very annoying indeed. Sorry for that.

Are you absolutely sure you are using the latest version 1.1? You can check in the About screen. The new version also has tabs.

When I try to follow your steps it works without problems...

It's possible to add custom TextMate-compatible syntax definitions to Textastic:

Unfortunately, I couldn't find a TextMate bundle for "Mplus", sorry. Maybe you can find one.

Usually a google search for "<programming language> tmbundle" brings up results if there is a syntax definition for that programming language.
