[MACTCL] how to handle the grab mechanism for toplevel dialogs in TkCocoa 8.5.8?

[zdia <z....@gm...>]

The issue is the following:

The application is doing some init work and meantime the main window is
withdrawn, then a toplevel dialog appears and when it is finished the main
window is raised with the application menubar.

The code is as follows:

wm withdraw .
initGui

		# the toplevel dialog is entering
		
		set oldGrab [grab current .]
		update idletasks
		raise $top
		focus $entrywidget
		catch {grab $top}     ;# this command is freezing the Mac menubar

		# the toplevel job 
		
		if {$oldGrab != ""} {
			catch {grab $oldGrab}
		} else {
			# catch {focus .}	;# not working either
			catch {grab release $top}
		}
		wm withdraw $top
		update

wm deiconify .
raise .
update



On Windows and Linux the main window with the menubar is appearing but not
on the version I have compiled:
http://github.com/downloads/das/tcltk/tk8.5.8-decarbon.tar.gz

Only the first application menu is activated so it is possible to quit the
application. If I insert additionally "grab .", "focus ." or "focus -force
." then even the first application menu is deactivated and the application
cannot be closed by menu.

Well, the workaround will be to comment the grab command out but is there
another (Mac specific) way to work with a toplevel window?
