Hi Cubus. This one has been aired on the forum before, but I can't quite remember the answer. I'm pretty sure that it is caused by a problem with an entry in the Autocomplete list. Try in IE, selecting Tools - Internet Options - Content. Then click on the Autocomplete button. You can then either untick the "Web addresses" box under "Use AutoComplete for", or you can try clicking the "Clear Forms" button. Either might help you.
