I was having this issue and it alsowas effecting only seemed to effect the Windows 10, and Infopath 2013 users.
After some examination I found that we had the page set. to:
<meta http-equiv="X-UA-Compatible" content="IE=10" />
it was thenThen I changed this to following:
<meta http-equiv="X-UA-Compatible" content="IE=edge,IE=11,IE=10" />
Tested goodAnd it is working fine.
Hope this helps.
