Why the slow response when switching between windows?

I experience slow responses when switching between Matlab and other applications and even when switching between the command window and the editor window. Anyone know of a fix, or why this is happening?

I experience the same if I have huge arrays in the memory. "clear" usually fixes this.

I do not have large arrays. I was running Matlab scripts with much larger arrays last summer on a Macbook and did not have this kind of issue.
