Occasional update issue

Recently switched from VSS to SVN. We all use TortoiseSVN as a client
and a few people seem to have a problem when doing an update.
 
2 users update the same file. u1 checks in and u2 does an update to get
the changes from u1 to his working copy. progress window appears and
shows a revision but no files show as updated. If you diff the file
with the repository then you can see u1 changes in the repository, but
the update does not pull down the changes to u2's working copy. I have
seen this twice on 2 different developers systems, but I have not been
able to reproduce it myself.
 
Any ideas?
