(nor with any other application), but that's just idle curiosity?<br></blockquote><br>My current theory is that the methods invoked by the shared instance<br>of NSDocumentController (that implement things like File:Open) work<br>more reliably because they aren't as brain-dead about autoreleasing<br>things that need to stick around through a modal event-loop as<br>CCL::CHOOSE-FILE-DIALOG seems to be. According to TFM (which I just<br>R'ed), the NSOpenPanel itself has to be explicitly retained on (at least)<br>10.6 and earlier, and I don't think that CHOOSE-FILE-DIALOG has ever bothered<br>to do that.<br><br><br><blockquote type="cite"><br></blockquote><blockquote type="cite">Maybe its because the deprecated #/runModalForDirectory:file:types: is causing problems under Mountain Lion even for apps like CCL that are not sandboxed.<br></blockquote><br>My first attempt at replacing the deprecated method with supported<br>ones caused my tests to start showing unpopulated directories; I'd only<br>seen that once before. Alex was apparently getting reliably good results<br>by mixing deprecated methods with their replacements; if his results were<br>universally reproducible, I'd have publicly sworn off badmouthing Mountain<br>Lion (since it'd have been obvious that the damned thing wasn't even finished<br>yet.)<br><br>One of the worst aspects of bugs where things get freed prematurely is<br>that the worst symptoms of those bugs may only appear if and when the<br>freed memory is reallocated, and when and whether that happens tends<br>to be dependent on lots of subtle little things.
