Hi, I installed Norton Utilities 15 on my Windows 7 PC and used the scan function in Norton Utilities. There was no problem. However, after I tried other functions such as disk cleaning, registry deframation, Firefox 11 started to behave strangly (see attachment). Some of the buttons in yahoo mail (e.g. delete, reply, forward spam, etc) also disappeared. I reinstalled Firefox 11 but the problems remain. Internet Explorer is not affected though. Any way to solve the issues appreciated.
P.S. Any way to post jpeg as the attachment?
