Hi richard,

Without seeing the code you're using to modify your Edit menu I can only guess,
but in the past I've found that routines which modify menu buttons by referring to
them as "menu" will work on the currently active menu bar objects, which may
not necessarily be what I want.


For example, if I need to update the contents of my own Edit menu I sued to write:

  put tMyMenuContents into menu "Edit"

But I found that if my update occurs when MC's menubar is the defaultMennuBar, I'll wind up modifying that one rather than my own.

So these days I tend toward very explicit references:

put tMyMenuContents into btn "Edit" of stack "MyMenuBar"


Thanks for the fast response...

But the menu is ready-made in a substack and i do not modify it in any way...?

Here is the script of the group "MetaCard Menu Bar" of mctools, and think here lies the ptroblem,
although o do not know where yet ;-)


on mouseDown
  if the short name of the target is "Help"
  then pass mouseDown
  local olddefault
  put the defaultmenubar into olddefault
  set the defaultmenubar to "MetaCard Menu Bar"
  lock menus
  if fnames is empty or button "Text" is empty then doinit

###!!!
  setupedit
  setuptext
  set the defaultStack to value(the last word of olddefault)
  set the defaultmenubar to value(word 2 of olddefault)
  --
  unlock menus
  pass mouseDown
end mouseDown

on setupedit
local otype
put word 1 to 2 of the selobjs into otype
if word 1 of otype is "card" and word 2 of otype is among the items of "field,button,image,player,scrollbar,graphic"
then delete word 1 of otype
else delete word 2 of otype
if otype is empty or otype is "card" or otype is "stack"
then disable menuItem 9 of menu "Edit"
else
enable menuItem 9 of menu "Edit"
if word 1 of the selobjs is "group" and the number of lines in (the selobjs) is 1
then put "Un&group/G" into menuItem 9 of menu "Edit"
else put "&Group/G" into menuItem 9 of menu "Edit"
end if
if the editBackground of the topStack
then put "Stop Editing &BG/T" into menuItem 10 of menu "Edit"


###!!! This appears in my medit menu with 4 empty lines before it, but why?
  else put "&Backgrounds.../T" into menuItem 10 of menu "Edit"
end setupedit

It happens when i switch from pointer to browse tool...
Any hints are very welcome :-)

You may have stumbled across a rare thing: a lack of robustness in Raney's code. :)


What recipe could I use to reproduce the side-effects you're seeing?

Have any of the other readers here encountered issues with MC's menu updates walking on your objects?
