Word COM AddIn and IE behaviour, help needed

[KeithM]

Hi all,

I have a COM Add In written in .NET C# and running on XP with Office 2003.

The add in stores some data for each document and displays this in a custom
toolbar when documents are loaded.
However when I launch word by clicking on a hyperlink, with a href to a
document, in IE, my custom toolbar does not appear.
I have to go into View\Toolbars and select it for it to become visible.
This does not happen when just double clicking a file on the hard disk when
using Windows Explorer.
I have tried deleting Normal.dot between launchings of Word but this makes
no difference.

I should add that in the "OnStartupComplete" AddIn function I use code to
physically make the toolbar visible but it still wont work from hyplerlinks.
It is as though something else is happening after I have recieved the Word
connection events that is overwriting my settings.

If anyone can throw any light on what is happening or how I can get round
this I would be very grateful as I have been 2 weeks looking for a fix so
far.

Yours hopefully!
