There is a HYSYS model open with multiple views open
The view of stream XXX is on top
User starts typing a Temperature for stream XXX
He seems surprised that HYSYS doesn't know that he has finished typing the temperature
To remedy HYSYS failing to do something he clicks on another view
Now, HYSYS understands the typing is finished, but also brings the other view to the foreground
So now the stream where the temperature was entered is obscured
User would then typically go back to the PFD to double click on the stream to view the result
This whole complicated sequence can be elegantly avoided by hitting the "Enter" button when finished. The stream stay in the foreground, the results are immediately visible.
So, give your "Enter" key some more love and you'll benefit greatly!
