Subject: -start experimental use of RunApplicationEventLoop,
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/3fbf8e7f3b144f649464f89c850efe43be847235?ds=sidebyside

-start experimental use of RunApplicationEventLoop,
-storing current event for menu handling, because otherwise we get a redraw problem in wxWindow::Update which is called from the menu tracking code
