I've always thought screen coordinates matched 1, because of this statement, and that window frame would have to be relative to 1. The screen: parameter on initWithContentRect:styleMask:backing:defer:screen: suggests that 2 is correct, though (and why isn't the method with more parameters documented as the designated init?). > And how is screen resolution taken into account? I have no idea. These are probably good questions for a dev list, since the docs give you just enough rope to hang yourself. I've also seen acknowledgments by Apple engineers on the xcode list that AppKit has bugs in switching displays and resolutions (or something like that), just to make life more interesting. -- Adam ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
