When trying to copy files from the server to my workstation or even from
one sever directory to another I got the following message.

Cannot copy ( name of the file ): Access is denied. The source file may
be in use.

I removed the client and then installed client 4.90SP2 Patch kit D and
everything works fine.

Is there a fix for this in the works? I see several other posts abouts
issues with client 4.91SP2 and Patch kit A.
