Currently I'm using SolidWorks 2005 SP2.0; however, the following problem is not new with this latest service pack:
I typically work with the performance option for assemblies to load components lightweight turned ON. (The same is true for Large Assembly mode.)
For some unknown reason, I repeatedly find that the performance option for assemblies loading lightweight is intermittently turned OFF without any user intervention. Often when I assume that lightweight loading is enabled and happen to be in a hurry to load a large assembly (especially when asked to do a quick presentation), SolidWorks ends up laboring to load each and every file while resolving them. (Maybe the program just senses my impatience level and acts accordingly...)
Please shed some light on the root cause of this highly undesirable intermittent system option toggle.
