Regarding self-closing alerts, on Mac it's easy
app.doScript ("""tell application "Finder" display dialog "Hello, World!" giving up after 2
end tell
""", ScriptLanguage.APPLESCRIPT_LANGUAGE)but on widows it looks like the only way to do it is making a vbs file as the doScript doesn't work in this case. I doubt that will solve your problem.
