double click required to close window

dlvbasys

local ui = require "ui"
local win = ui.Window("sample")
win:show()
while true do ui.update() end

if you try to close window (by clicking X top right for example) , you need to repeat it twice
depend on setting in studio either to show console window when running or not
if that setting is OFF , everything seems works like supposed to be
if ON, then you have to force clicks to close window

Thank you for this bug report.
I will investigate this bug.

Well I have some news.
It's not really a bug. Here you are using an infinite loop to process ui events using ui.update

When doing so, the onClose() event is processed during the first call to ui.update() but the next call to ui.update() didn't have the time to actually close the Window (hence the second click needed).

After closing the Window, the program still runs forever (you must close the program using the Stop command in the IDE).

You should not use infinite loops when processing ui events.

The correct way to do this using your example is :

local ui = require "ui"
local win = ui.Window("sample")
win:show()
while win.visible do
    ui.update()
end

That way, the window closes immediately and the program exits.
