No, that’s not necessary. And can you send the information regarding the error from the Console (found in Applications > Utilities) to support@devon-technologies.com? Then I can check what caused this message to appear.
I had the same thing happen to me the first time. That was over 24 hours ago, so I don’t think I have the messages anymore. Worked fine after that fist time though.
Scribbler is a new version of the application and it is not a signed binary. As such, OS X demands you “okay” its launch as a security measure, before running it the first time. If you don’t OK the dialog, the app won’t launch and DTP won’t be able to find/use it. Given this dialog box can be hidden, this would cause this problem. It’s what I saw, when I noticed OCR wasn’t completing and DTP was effectively “hanging” with a beachball.
After first launch, when you click “okay” to let the application run, OS X will write a signature in the app and it can launch without issue.
The DEVON folks could get around this by signing the scribbler application binary, but it may be a bit of work to sign an application that’s a beta.
