Wait a minute - why are you using NSApp in an NPAPI plug-in? NPAPI plug-ins could be loaded into a non-Cocoa browser such as Firefox that will not have an NSApp set, so this seems inadvisable (and could possibly be part of what is causing the weird behavior you’re seeing). Apple seems to suggest that this sort of thing should not be done in an NPAPI plugin: http://developer.apple.com/mac/library/documentation/InternetWeb/Conceptual/WebKit_PluginProgTopic/Tasks/NetscapePlugins.html#//apple_ref/doc/uid/30001250-DontLinkElementID_1 > • Use platform APIs sparingly.
