Hi Community,
I am pleased to report that our engineering team has just released some changes designed to correct this problem. I was just able to load the multi variation listing interface through Internet Explorer 7.0 from my end, so things are looking good so far.
If anyone continues to have trouble with this functionality, please let us know by contacting our customer support team using the form on the following page: http://www.auctiva.com/help/requesthelp.aspx#
