I will eventually install IE9 on my Win 7 systems. DDNS server used for remote online real time surveillance with three security systems currently in use does not support IE9 . Sent an email to the company's support last night asking for the 'patch' to make IE9 compatible. All my Win 7 machimes are in use viewing my security system live cameras at one time or another so can not install at this time. Anyone using IE9 have any information/experience good or bad to report.
