Hi. I've just upgraded from Vista 64 to Windows 7 Home Premium (64) and am now unable to follow some hyperlinks, download files from the internet, or even activate my account to this site from within the activation Email. I move the mouse over the hyperlink (or download icon), the mouse arrow changes to a finger symbol (as expected) and I can press the LH mouse button all night with no avail ... absolutely nothing happens, no error messages, no dialogue boxes - nothing. I've compared my explorer security settings and exactly the same boxes are ticked as for my laptop, I've even re-installed Explorer 8 with no change to this problem. I really need to download an updated driver from Sitecom Support so that I can install and use my Wireless Card, but I simply cannot get this computer to run or download the file. What's going on? Any help to resolve this extremely frustrating problem would be very much appreciated. Thanks W Souter Westbury, Wilts.
