Hi,

We're using Intel Core2 DuoT9600 at 2.8Ghz on Win7 64 bit 4Gb Ram.We are editing an assembly of 540 parts, made up of several sub assemblies and several parts. On SW2010 this performed fine. Now it is very sluggish, when pressing middle mouse button to rotate their is a several second lag before the rotation begins. Once it is rotating then it performs fine and rotates smoothly. Is this a SW2011 thing, or is our system finally getting to old for SW. My laptop, similiar spec (Dell Precision M4400) is only a year old.

any comments apprecaited
