On Macintosh, why do the tool palette and graph info box fail to stay attached to a window when moving the window around? And why do these fall in the shadow of the main window?
The technology used to implement these grouped windows in Igor Pro 6 is no longer available in Cocoa, which is Apple's current graphics API. We've done the best we can to replicate the Igor Pro 6 behavior in Igor 7 and later, but unfortunately the OS simply does not provide the functionality we need to get the exact same behavior.
