Internet Browser issues - clients reporting blank screens?!?

Internet Browser issues - clients reporting blank screens?!?

Is anyone else experiencing issues with IE7, IE8 and IE9? we have several customers who due to being not for profit are working on older browser versions (although as per ZOHO website - these are supported) but since last Thursday am - they havent been able to get on - this has been logged but all we hear is 2-3 days we will get an update. As its recruitment some of our clients have 200-300 applicants and its become a real issue for us to do everything for them - so i was wondering if anyone else was experiencing the same issues as we are?
