Recently, I have come across a problem of using IE6 to access CK-ERP.
An explanation of the problem is available at,

Since I had been using multiple button tags in a number of CK-ERP
screens, IE6 access will result in some rather unpredictable and
hard-to-trace anomalies. As far as I know, IE7 had this problem rectified.
Best Regards,
