32-bit error with F-secure

About 1 month ago we started having this problem withF-secure.

When opening an assembly (ab. 1000 parts) SW gives few weirderrors, turns menus black, hides part names and it is impossible togo on.

If F-secure is closed, everything runs fine. If only firewall isdown, it is no help.

If not logged in to PDM (Workgroup), everything runs fine (withF-secure on).

---------
This is with 32-bit SW (2008 & 2009). 64-bit SW runs withoutproblem.

Our IT is working on it but would appreciate any tips for this ifanybody solved this.
