I get this message a lot especially when working on assemblies or when switching between multiple open parts. I'm not working with giant assemblies or anything but it seems to be happening very frequently. Does anyone know how I can avoid this or if there is a solution to the problem that Pro/Engineer is encountering. I am working with WF5 Schools Edition.
First make sure you are running the last release (m060 I guess), try to reproduce the same operation in another workstation if possible, If you are using school edition you probably are from an Univercity, see if they have active maintenance and ask for the reseller for support.
