Hi all, I'm stuck with what appears to be an embarrassingly simple problem with a new small document based app I'm writing. I can save files and open them perfectly well, and when the app is running, a double clicked document will open correctly. However, when the app is not already running, when I double click a document, the app launches, loads all of the data from the file (I've checked this by having it write info out to a text file), but then does not call windowControllerDidLoadNib. I imagine there could possibly be something in the target settings or possibly interface builder that needs setting, but I can't think what it could be. Any nudges in the right direction would be greatly appreciated.
