fix committed to HEAD:

	* macosx/tkMacOSXCarbonEvents.c
	(InstallStandardApplicationEventHandler): on Mac OS X Leopard, replace
	the 2005-11-27 approach of installing the standard application handler
	by calling RAEL and immediately longjmping out of it from an event
	handler, as that now leads to crashes in -[NSView unlockFocus] whenever
	HIToolbox uses Cocoa in Leopard (Help menu, Nav Services, Color
	Picker). Instead call InstallStandardEventHandler() on the application
	and menubar event targets, as Leopard ISEH finally handles these
	correctly. Unfortunately need a HIToolbox-internal SPI to retrieve the
	menubar event target, no public API appears have that functionality.

I will further investigate if it is possible to use public API to  
replace the GetMenuBarEventTarget() SPI, as this is acquired via  
TkMacOSXGetNamedDebugSymbol(), and may not available in future  
versions of HIToolbox.

backport to core-8-4-branch forthcoming...

Cheers,

Daniel
