Starting September 1, 2021, Mercell will no longer actively support the Internet Explorer 11 (IE11) web browser for Mercell Source-to-Contract (previously known as Negometrix3 and Negometrix4). 

Internet Explorer 11 has become a legacy browser since its release in 2013, and is no longer supported by Microsoft.

This means that from September 1st onwards, issues that arise from using our software with Internet Explorer 11 will no longer be fixed.  

We recommend that users transition to modern browsers like Microsoft Edge, Google Chrome, or Firefox.

If you choose Microsoft Edge, you can use Internet Explorer mode.

Microsoft has a guide for this:
