Using PDMWorks workgroup 2008(Server version SP4.0 and Add-inversion SP5.0) and SolidWorks 2008 SP5.0

We have 7 users and when anyone takes or releases ownership of aproject, everyone else who has Solidworks open is frozen until thattask is completed. On large projects this can take several minutes.

Is anyone else having this issue and what would cause this tohappen.

THANKS
