<p class="MsoNormal"><span style="color: black;">It raises an
error because of Object >> #runningWorld associates
the world with the active process and not the current UI
(I’m not saying it’s wrong; I just don’t know because this
all is way beyond my current skill level so I’m just
observing Squeak evaluates the example ok). The comment even
mentions: “This method could answer nil, if not in an UI
process!” which seems to be our case…</span></p>

This is fun. You keep finding corners in the system! Now these work:
<br>
<br>
[1/0] fork.<br>
5 seconds asDelay wait.<br>
"self confirm: 'test'"<br>
"self request: 'Test' <br>
initialAnswer: 'initial answer' <br>
orCancel: [ ^nil ]"<br>
"FillInTheBlankMorph request: 'What is your favorite color?'"<br>
"<br>
menu _ MenuMorph new.<br>
1 to: 3 do: [:i |<br>
entry _ 'Line', i printString.<br>
sub _ MenuMorph new.<br>
menu add: entry subMenu: sub.<br>
#('Item A' 'Item B' 'Item C') do:[:subEntry|<br>
sub add: subEntry target: menu <br>
action: #modalSelection: argument: {entry.
subEntry}]].<br>
menu invokeModal."<br>
<br>
(uncommenting the queries one at a time)<br>

<p class="MsoNormal"><span style="color: black;">Also, I’ve
realized there are ‘sub-cycles’ run inside the UI in some
cases; I’ve never really noticed and have no idea whether
this is something to worry about: in Squeak or Pharo, when I
run the “confirm:” test the inactive UI that evaluates the
confirm: dialogue runs its subcycle which means that until
the dialogue is dismissed there are two cycling loops – one
belonging to the current UI and one belonging to the former
UI running the dialogue…

I don't like that design. It means that there are times where the
world is not in control, and then, for example, animations and
stepping are halted. I removed a couple of those in Cuis, but some
still remain. We'll keep cleaning, as usual.<br>
