The September 9 patch cycle brought KB2977629, the Cumulative Security Update for Internet Explorer 11.
Never experienced any issues with IE security updates in the past, I was surprised to find out that ieframe.dll caused a crash in Internet Explorer 11 or Cubase Elements 7.
To test the hypothesis, I removed the patch and the issue seems to be gone.
Was it a faulty patch or a faulty installation?
Can this issue be resolved?
