Hum... sounds like an uninitialized variable.

Let me know if I am wrong, but does it happen when the attributes editor is
not open ?

Hello!

When opening the menu editor, after saving, and maybe in other
circumstances I get the following error:
-----------------------------------------------------
can't read "vTcl(gui,ae,canvas)": no such element in array

Normally I can simply "click" it away.

The stack trace shows the following:
...
    #
    # Update Widget Attributes
    #
    set fr $vTcl(gui,ae,canvas).f2.f
-->^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    set top $fr._$vTcl(w,class)
    update idletasks
    if {[winfo exists $top]} {
        if {$vTcl(w,class) != $vTcl(w,last_class)} {
 ....

and the call stack:
(procedure "vTcl:prop:update_attr" line 15)
(procedure "vTcl:select_widget" line 23)
(procedure "vTcl:active_widget" line 15)
(procedure "vTcl:save2" line 93)
(procedure "vTcl:save" line 9)
(code segment 1)
("uplevel" body line 1)
(procedure "tkMenuInvoke" line 47)
(command bound to event)
-------------------------------------------------------

Best Regards
