Drawing very laggy/unresponsive

Hello.

We have a drawing that for whatever reason is very laggy and unresponsive.  Commands/mouse movement lags about 5-6 seconds behind.  It isn't a super complex drawing/assy.  The drawing is saved locally, ie not on a server.  I am using a new computer that was put together specifically for Solidworks....

Any ideas?
