I'm running MATLAB R2012a on my mid 2010 Macbook Pro (2.66 GHz i7, 8GB RAM)

When I first open MATLAB and do some work it runs quickly, but after an hour or two of work, it becomes very sluggish and delayed (the time between clicking or typing something and the action actually being performed increases). 

The only solution I've found (more of a workaround) is completely killing the application and opening it again. Does anybody have any idea as to why this happens?
