Long process time to remove parts from assembly

Hi,

Me and two other users have experienced that SolidWorks sometimes taking alot more time to remove parts from assemblies the last past days. So far, I have not been able to figure out why it sometimes take much longer time than it does for other assemblies. I guess that it might have to do with the assembly itself... By long time we are talking about 5-10min or even more.

The long process time is for sub-assemblies, parts and toolbox parts. So I see no difference in behaviour depending on the format.

As far as Iknow, there is no change in the settings (I will check if there have been any unwanted changes. But I currently do not see why the settings could have changed).

We are running SolidWorks 2012 SP5, Windows 7 64bit.

Any thoughts, ideas or comments that may resolve this issue is most welcome .
