[Gnumed-bugs] Minor bug in GUI "list encounters"

[Busser, Jim]

When first entering this window, which defaults to no selection of encounters, 
it is possible (without an encounter in focus) to click

        Edit

which will open an editing window with all values blank.

It was possible to populate this and then *try* to save it --> results in a UE 
which I did not bother to attach.

However if, before clicking "Edit", any encounter was selected, then it is not 
possible to achieve this.

Suggested solution, if possible, would be for the window to open with focus set 
on the newest (active) encounter by default.
