Hello List,

Have a strange issue. This particular user has several third party Excel
add-ins that he uses. Every few days they disappear completely from the
add-in list but the default add-ins stay.

Does anybody have any idea on what could be causing this? The times at which
they disappear seem to be completely random. Sometimes it could be 2 days,
sometimes 4 days etc.

Windows XP
Excel XP

Thanks for your help.

Cheers.. Ben
