Comment 8 for bug 179936

1) Forget about comment #7; as I already thought this seems to be a misfeature in Metacity: Bug #379242. Though, if there is another solution that does not have this issue, you can update the patch.

2) As you said by im, I did omit this part of the patch:

+ if ([winfo exists $priv(wpageversion).l0]) {
+ return
+ }

...to fix this error:

can't read "priv(wpageversion)": no such element in array
can't read "priv(wpageversion)": no such element in array
while executing

Can you take a look at this?

3) Maybe it is a good idea to add similar code to the History, Edit Contact, and Contact Actions dialogs.
