Using v 4.1.3.xx on Win7

This is surprising to me but not really a significant issue. That is, if you select the menu item Maintain Library and then the Maintain Files Tab, clicking the CLOSE button will start maintenance just like clicking the Maintain Now button. I kind of expect CLOSE to close the dialog without taking any additional action. So I try to remember to click the red X in the upper right corner of the Window.

Just noticed that clicking the CLOSE button on the Tools Tab will also start up maintenance.

Are my expectations wrong that CLOSE should not start any maintenance?
