Seems to be a problem with javascript - see third screenshot. Replying to a ticket results in a message warning that the publisher of the *.js file can't be verified (see screenshot):

The same issue could be reproduced in IE11 as well, so it's totally IE's legacy.

Hi Guys,

We do have certain compatibility issues in Microsoft Edge browser. Since it is relatively new, We haven't concluded testing the product in the above mentioned browser.

However, With regards to the script error, Please try the below suggestion and see if it helps.

• 
  Open Internet Explorer by clicking the Start button . In the search box, type Internet Explorer, and then, in the list of results, click Internet Explorer.
  
  


• 
  Click the Tools button, and then click Internet Options.
  
  


• 
  Click the Advanced tab, select the Disable script debugging Internet Explorer) and Disable script debugging (Other) check boxes.
  
  


• 
  Clear the Display a notification about every script error check box, and then click OK.
  
  

Any status update on this issue?  With Windows 10 coming out and ever increasing Microsoft Edge use, I imagine this will become quite a large issue for you if not resolved.
