IMPORTANT UPDATE from AbleCommerce
Microsoft has confirmed that there are known issues when using the latest IE10 browser and certain code that might be in Asp.Net 2.0 or Asp.Net 4.0 sites. All AbleCommerce 7.0.x stores are affected by these issues, so you should carefully read the available options and take corrective action.
2. ImageButtons do not work in IE10 when using .net 4.0 and older
Microsoft has made an official patch available for one of the issues. It is unknown, at this time, if Microsoft plans to release another patch for the second issue. As such, AbleCommerce is providing a work-around that can be applied to your AbleCommerce store.
You should fix both issues by following the instructions found on the AbleCommerce help site.
