Hello,
if I am using a split source window showing different parts of code in the upper and lower part of the screen the menu command 'Go Back' changes the displayed contens of both windows, not just the one of the active window...
If, for example, your lower source window is the active one, and you use 'Go to Definition' and then 'Go Back', I would have expected that the previous screen is restored. This, however, is not the case, because also the view of the upper source window is changed and shows the same code selection as the lower window, even if the code selection was different before pressing Ctrl+G. This is unexpected and inconsistent, because, e.g., Ctrl+I only applies to the active source window (as expected).
Can NI reproduce this issue, and would it be willing to fix it? 
Thanks!
