I use Excel 2000 on Windows XP in a corporate environment, on a laptop.
I load two addins (PUP v6 and autosafe). Every week or so, these addins
disappear from the addin manager and are therefore not loaded. I keep
the addins in a non-standard location, so I must browse to the correct
folder to add the addin to the addin manager. I have been doing this
for some years without a problem. The problems began when I moved
offices;I suspect it is change in the way my Windows files and settings
are handled between my laptop and the network file server.

If the addin settings are stored in the registry, then does this mean
something is happening to my registry settings?

My home directory is mapped to a network file server and is
synchronised using the Windows "make available offline" feature. I
suspect a problem with this although I have a non-roaming Windows
profile.

would appreciate some hints. For example, what files are linked to
Excel's handling of addin preferences? the .xlb file?

regards,

Tim
