Errors and crashes when creator exits after running a script

Original Post by: chrisell Thu Oct 7 17:42:41 2010

I've got a scripting problem that I'm not sure how to resolve. The script I've written runs cleanly when in use, but whenever I've used it, I get a couple of error dialogs as Creator is closing.

Note the errors never come up when creator is running, only when it's closing down.

The first one is DuumyGLWnd: mgfltx.exe - Application error. When I OK that one, I then get a pure virtual function call error (R6025). When I OK that one I get another DummyGLWnd error. Only when I OK that third error is Creator finally shut down.

The script is designed to parse a model and turn off sections of it based on some of our custom attribution. eg if we have a model with 20 different colour schemes in it, only make one of them visible without having to hunt through the hierarchy and do it manually.

Any ideas ?
