Yes I know, JUCE_MODAL_LOOPS_PERMITTED=1 is evil …
With JUCE 8, the following code was working perfectly :
juce::AlertWindow::showMessageBoxAsync(juce::AlertWindow::InfoIcon, juce::translate("About MyApp"), "message", "OK");
Now with JUCE 9, it is still working on Windows and Linux but now on MacOSX the alert window appears during 1 millisecond and disappears …
If JUCE_MODAL_LOOPS_PERMITTED=0, there is no problem (but of course in my project, other problems arise …)
