Hi,

we sometimes get an error when creating a new file in source control via web access. This happens after selecting a file via browse when the file normally gets uploaded. The following window pops up:
Message from webpage
'getElementsByTagName(...).0.value' is null or not an object
The upload is cancelled. The error appears only for a single user and only for a few hours / days and then everything seems to work fine until another user who was able to work just fine gets the same problem.

The error appeared on Internet Explorer 8, but when using Firefox 3.6 it worked just fine. After making the upload with firefox the error was gone with internet explorer too.

Any ideas what this relates to and how to fix it?
