Undo problems.

[bob . fletcher]

Hello,
     First,  vtcl is great.
  
  I just grabbed v 1.08 of vtcl.  I'm on HPUX.   wish4.2.

   I 

Make a top level.
Add a frame.
Add a canvas in the frame.
Do an undo to get   rid  of the Canvas.

Next I get a continuing stream of error messages saying
that the  ' bad  window path name' 


 Stack Trace says.


bad window path name ".top.frame.canvas"
    while executing
"winfo toplevel $vTcl(w,widget)"
    invoked from within
"if {[winfo toplevel $vTcl(w,widget)] == "$target"} {
        vTcl:place_handles $vTcl(w,widget)
    } else {
        vTcl:select_widget $target
       ..."
    (procedure "vTcl:wm_take_focus" line 8)
