#1155 Quit in .onUserAbort behaves weirdly

[Marshall]

Latest 3.0, haven't tested older versions.

Calling Quit inside .onUserAbort acts like Abort (we don't quit), but when you then click Next/Install, it quits.
I'm guessing the quit message is posted but not handled until the next event.

Yes, it's silly to call Quit in .onUserAbort, so this is very low priority - but it should quit immediately, or be ignored completely.

Apologies, right now I cannot replicate this using a simple script. It's definitely happening, but it appears that something else in my script is contributing to the weird behavior, although I don't know what yet. I'll post an example when I figure it out.

Okay, replicated

OutFile "example.exe"

PageEx custom
    PageCallbacks __onPageShow_welcome
PageExEnd

Section dummy
SectionEnd

Function .onUserAbort
    Quit
FunctionEnd

Function __onPageShow_welcome
    nsDialogs::Create 1044
    nsDialogs::Show
FunctionEnd

I'm guessing this only happens on custom pages?

Function .onUserAbort
    SendMessage $HWNDPARENT 0x408 0 ""
    Quit
FunctionEnd

seems to work but it is a bit of a hack.

Indeed, it appears to be due to nsDialogs taking over the message loop.
