Losing Add-Inn Functionality
 

Hello,

I originally posted this under a different subject but now that I have more
clarity on the issue I believe that I should post this under something more
suitable.

We have a user who has several third party add-ins that he uses on a day to
day basis. These add-ins create additional menus within Excel so that you can
access their functionality.

Almost daily these menus disappear from Excel and the functionality that
these add-ins provide, terminates. However, when you go to the add-in list in
Excel these add-ins are still listed and are ticked. The way to restore the
functionality of the add in is to untick/retick the box and all is ok. Can be
quiet annoying when having to do this (sometimes) several times a day.

These add-ins are quite common in financial markets (Bloomberg, Reuters,
PowerPlus Pro) and we have several users using them without any disruption.
We have deleted the users profile and rebuilt the machine, but unfortunately
this issue still ocurrs.

Can somebody please help me out with this?

Many Thanks, Ben
