Toolbox - multiuser problems

Hi
We are using SW 2008 SP5.0 and have serious problems with toolboxand working in multiuser environment.
When my colleague has a model open with for example a toolbox part"hex-bolt ISO4017" I cannot ad the same type of part in to mymodel.

I recieve the error:
Toolbox - Drop File Error
Erro: The toolbox part file `S:\Construction\SolidWorks\SolidWorksData\Browser\iso\bolts and screws\hex bolt gradeab_iso.sldprt iscurrently being modified by `user`. Please try again in a fewmoments.

We have put the SolidworksData folder on a common server(read-only).

In tool/options we have "create configurations" checked (we havealso tried the create parts alternative).
We have changed the "Hole wizard and toolbox folder" to our commonserver:
s:\construction\solidworks\solidworks data\

Does anyone have the perfect solution for working with toolboxparts in a multiuser environment and at the same time having thepossibility to "pack and go" and deliver the assembly to orcustomer without loosing any data?
