Looking for a little help...

I have an external process that I am starting that will take a while (enabling a network interface that doesn't return until DHCP returns an address) and want to alert the user that this will take a while.. so I am displaying (or trying to) a message box prior to calling this process:

displayMessage( "this will take a while...);
os.execute( "myExternalScript" );

problem is the message box doesn't pop up until after the os.execute() returns. Is there a way to wait until the message box is up before control is captured by the os.execute()? I tried a short murgaLua.sleep(50) to allow a context switch but that didn't help. Any ideas?

...
function displayMessage( msg )
do
window = fltk:Fl_Double_Window(...)
box = fltk:Fl_Box(...)
button = fltk:Fl_Button(...)
...
end
window:show()
end

check that the window is not nil before launching your network script

Could also wait for the user to hit an "OK" button or some such to actually launch that external script.

Thanks for the advise, I'll try a couple of things..

Maybe try adding Fl:check() before you run the executable.

Also, Fltk has a built-in message dialog function, so unless you want something that looks a particular way you can use this

fltk.fl_message("This is my message")

You might look into fl_choice() if you want to give the user the option of cancelling the upcoming action.
