Not had that problem reported before, does your browser window close or do you get an error message?
Could be a problem with your internet browser, might be worth deleting temporary files in internet explorer, to do that go to Tools, then internet options, then select delete files, in the centre of the dialog box.
The browser window closes completely and I go back to the desktop screen and only happens when accessing these topics. All others before and after I can get in with no problems. I did what you said but still the same.
Obviously if no others have reported it, it must be my system. Thanks anyway.
