Costa: Your wget was a real good one. Viewing the page source in explorer reveals the same page content and it's identical to what you have already posted, a java script command to close the page.
I have just spend my morning online chatting with Cisco support and I have to get back at my earlier remark on their service. For products like this you have to contact Small Business Support. That's something Big Business Support could have told me too, but they're forgiven.
Of course I had to go through the whole script of trying different browsers, editing the registry on my server (!) etc. The WebEx application crashed, so I had to go thought it three times, but the guys are skillful and helpful. They even tried to reproduce our problem on a machine in their lab. Very good. The last guy eventually suggested that this new firmware may not be fully compatible with my hardware revision, or that something is just broken.
Cisco doesn't recommend firmware downgrades and they didn't recommend me to use the switch in that state. Instead they offered me to replace it. And the best thing is: They will replace it in advance. My whole network depends on this switch, so I am really helped out here.
These switched come with a 5 year warranty, and they're not on the market for 5 years yet, so your switch is probably covered by warranty too. So I recommend you to make use of Cisco's excellent service too.
