After further investigation I noticed

Clicking on "Display information concerning current system"
Does the following
1) when no application is executing
   - display the system information in the output/General panel
   - focus the output/General panel

2) when an application is being executing inside EiffelStudio
   - display the system information in the output/General panel
   - focus the output/General panel
   - display the execution information in the output/Debugger panel
   - focus the output/Debugger panel

Then, to the user, it seems only the execution information are being displayed ... but if you select the output/General panel, you'll get the "system information"


So now, what could we do? 
A) Add a new "execution information" button/menu, and separate the 2 functionalities  System/Execution
B) keep current behavior
C) Display the system information for 5 secondes, and then focus on the "Debugger"'s output?
D) ... allow to have multiple "Output" tool panels, and being able to keep selected a particular output (which could be appreciable for time to time)

For now, I would go for A)  and think about D) since it would also been quite nice to have multiple edition of the "Feature tool" for instance ... But I am not this would be that easy to achieve for now.

(note: we should also rename the "Debugger" output, into "Execution" output)
