I am using IE11 on Windows 10 Enterprise, 64 Bit, German version. Up to a few months ago I was able to see the call stack in the IE 11 debugger, as usual.
However, since a couple of months, I am not able to see the call stack in the debugger anymore. This item is called in German in another way, but this is not important. My question is: How is it possible to turn on (to show) the call stack in IE 11 debugger again?
Below, please find out a screenshot of what I see in my IE11 debugger currently:
NOTE: Reading this documentation
Debugging Script with the Developer Tools
did not solve my problem

After many tries and errors, I found out that the Call Stack pane was actually minimized. In fact, only after I went over the most right-down scroll bar with the mouse and tried to "drag" it up , I was able to see the Call Stack again. Unfortunately, on the screenshot I gave, it looks like the Call Stack is missing, whereas it is actually minimized.
Hope this helps other members having the same problem.
