hi all

we have a very strange problem. since we installed our excel vsto plugin on
one of our test machines, it's not possible anymore to double-click an excel
file and make excel open it.

In the Addin_Startup method, we simply create a menu and attach an event
handler to it in a separate method (CreateMenu). when i remove the call to
this method, it works again. it also works on my development machine where
the addin is installed by visual studio directly.

when i search in the internet, i found lots of people having that problem,
but no solution.

does anybody have a hint what to do ?

thank you in advance and best wishes
