I've been using Mirc for a while now, but in the last few days, when I try to open a link, like a pass to a site, it won't load and gives an "Invalid Syntax Error" message.
Microsoft stopped allowing IDs and passwords to be embedded in URLs used by Internet Explorer. After applying the patch, if user information is included you'll get invalid syntax error, read http://support.microsoft.com/default.aspx?scid=kb;en-us;834489 which has details about why and "workaround"
