The Finder Application For MacBook Pro

Recently (as of today) when I open my finder application it tries to shrink away, back into the toolbar. I assume that I may be clicking the icon twice but the delay between my click and the window opening must be growing longer as I have never had this happen before. Even as I type this I notice that the keys are not responding as quickly as previously... I have not used up the storage space on my Mac nor do have a particularly troublesome one either A.K.A. never needed to ask youtube how to fix it ;-). Is my Mac just suffering from a lack of shut-down time or is this more serious?

Thanks
