I am sorry if I have previously used the wrong place to put my question. Most times after I have had the computer switched on and after 30 minutes approx. I click on a app and it just "hangs" with the blue circle going around and around and after a couple of minutes stops. You can click on the app again and it just does the same and the only way you can continue is to shut down and reboot and then it seems to be OK for most of the day. The same thing happens whether you choose to shortcut from the Start Page, or the Desktop or the Task Bar. Can someone please tell me what it is and if they know of anyway to resolve the issue. Thank you.
