Nor will 1.9.4 run on Lion 10.7.2.
It throws an initialisation error 13 on start-up then crashes.
Console shows PowerStructure: kCGErrorInvalidConnection: CGSGetWindowTags: Invalid connection
and
PowerStructure: kCGErrorFailure: Set a breakpoint @ CGErrorBreakpoint() to catch errors as they are logged.

It still runs fine on OSX 10.6.8 so it is probably a 10.7.X issue.

The problem is the new Lion issue with the Library. Here is a solution for any others using Lion OS who might also be having the same problem with this outstanding app.

the app is tryng to read the validation code but can't get permission?

Of Course. The answer is to reset the ROOT permissions.

Here is a quick fix:

1. Click on Finder, and hold the Option key, and select Library

2. Click on Get Info

3. In Sharing and Permission, click on the + sign, and add your User Name, with Read & Write permission.

It should now work fine if you have validations left - you only get three, so you are screwed if you forgot to de-validate when you got your new computer.

Progress report:

After successfully getting the app to fire up (after realising the LION issue with Root permissions - no thanks to the company, the Validation panel says,

There was a problem registering. The server says:

You have used up the three registration credits available and will need to uninstall the program from one of the other computers that it is currently validated on.

NOTE: Remember to use the UNINSTALL program on this other computer or you will NOT get the validation credit applied back to our online database!

If you don’t understand it, please report this message to ScriptPerfection tech support. It has been placed on your clipboard so you can paste it into an e-mail.

The oddball validation system has eaten the app.

This validation system alone has cost me two days of work - can you developers give that back? No! The whole trial of getting Power Structure to work has taken the better part of two weeks and I still can't get it to run because of the locked up validation system.

Thee must be a better way to treat paying customers. People change computers. That is a fact. With several hundred apps and thousands of documents one has to trust the Apple Migration Assistant - well it does not work with apps like Power Structure that were clearly broken at the time. Why not figure a way to punish the pirates - not paying customers. Using these flaky licensing systems is just poisoning the way I feel about buying any more apps from from this stable. I feel obliged to send notifications of problem software to fellow writers. People like me also let out our experiences be known on MacUpdate and other professional and amateur web sites. You are shooting yourselves in the foot. I can't believe businesses can actively try to kill off their loyal customers and limit other potential customers ever trying the organisation's products.

If I had known about the problems I would encounter with this app (and Dramatica and MM Screenwriter) I would not and could not now recommend them to anyone.

Great apps completely ruined by fear of pirating. Crazy! Contour is just as good and half the price and has fantastic support and Celtx is free and beats the pants off MM Screenwriter at that price.

Go figure.

Aghh! the font jaggies are driving me nuts. The developers need to do something about making better font resolution and antialaising.

Well, from the horse's mouth. The design team do not intend to resolve the font issue. This makes Power Structure - an otherwise brilliant app - impossible to use on a Mac. Fonts are seriously jaggie and lines bunch up together with no line spaces. The text is virtually unreadable. My impression from the reply to my query is that Power Structure may get a little tizzie-up here and there under the guise of a higher version number but their actual reply indicates clearly that they do not intend to continue development. Here is their reply: 'According to development, that would require a rewrite with more modern APIs, and we don't have any immediate plans to do that.' So I now recommend other apps such as Scrivener and Plot Control and The Marshall Plan, if and when Evan Marshall finally fulfills his year-old promise to release his app. What a pity. Power Structure is the one application most tightly fitted to actually developing a story and leaving the author to change and alter the app to suit their own needs. Smart, flexible and intensely useful. Get with the times guys. Power Structure could be extra special and you are deliberately killing it. Have you realised the connection between this app and Star Wars? You are missing a fantastic marketing opportunity. Nuts!

Well I tried cleaning up my data base and pruned everything to the bare minimum - and Caboodle just chugs and lugs along at its own snail's pace. It is driving me nuts - and I paid for this. I'm going back to iNotePad, it is not as pretty and has not been updated for ages, but hell it works. I'll keep my Caboodle license in iNotePad in case Caboodle ever does what it is supposed to do - at least I will be able to find it if and when I need it again. This is not really ready for commercial release.
