CommandBarComboBox .Change event stops working after a while

[Karsten_Markmann]

Hi
I am writing an Office Com Addin application for XP and Office 2003
I am writing i Visual studio 2003 VB.
I have a made a custom toolbar with some buttons and a combobox on.
The bar loads OK in Word, Excel and Outlook.
The buttons always work in all applications. The Combobox .change
event always work from Outlook and Excel, but it stops work in Word
after a while.
Has anybode any ideas of what can cause this behavior? Any help
appriciated.

Here is a snapshot of my code:
-----
Class declarations:
Public Class Connect

Implements Extensibility.IDTExtensibility2
Private WithEvents cmbSearchCoveo As CommandBarComboBox
Private WithEvents cmbSearchCoveoButton As
Microsoft.Office.Core.CommandBarButton

------

Private Sub cmbSearchCoveo_Change(ByVal Ctrl As
Microsoft.Office.Core.CommandBarComboBox) Handles
cmbSearchCoveo.Change

ShowIEURL(HTTPSEARCH & cmbSearchCoveo.Text)

End Sub

-----
'adding the combobox to the toolbar:

cmbSearchCoveo =
cbrNewToolbar.Controls.Add(Type:=MsoControlType.ms oControlComboBox)
With cmbSearchCoveo
.BeginGroup = True
.Visible = True
.Style = MsoComboStyle.msoComboLabel
.Caption = "Fritekst søgning:"
.TooltipText = "Fritekst søgefelt i KiC systemet.
Søger i alle dokumenter efter det skrevne."
.Tag = "SearchCoveo"
End With
