CommandBarButton events don't fire after new document.

[Tommie Johansson]

Hi!
I have a problem with word addins. When I create a custom CommandBar with
CommandBarButtons (yes, I define them at class level so the garbage collector
won't kill em) they work fine, until I click "New document" toolbar button.
The events wont fire when the "second" word app starts.

I've tried the following code ( posted by Wei Lu [MSFT] in response to the
"CommandBarButton click event does not fire" 1/17/2007).

Can someone please at least try the code and see if you get the same error??

thanks

Hi =?Utf-8?B?VG9tbWllIEpvaGFuc3Nvbg==?=,

Did you also declare a TAG property for the button? Word needs that to "sort"
which window is calling. I don't see an assignment to the Tag property in the
sample code...

Thanks Cindy.
It works if I put something in the tag property!
