I recently re-installed leopard with a clean install because I was noticing some slowdowns. Now I am having problems closing tabs and windows. When I click to close a tab (tried both with the touchpad and click button) I get no response on occasion. I have to click around over and over until it finally gets the click. I'm noticing this in both Safari tabs, iChat tabs, and all windows. I'm not noticing any click problems with anything else besides closing tabs and windows. Thanks.
