Explicitly schedule the initial check for updates after a fixed short delay Explicitly schedule the first check after startup to run after a short delay defined in PUI_STARTUP_DELAY. This was always intended but not correctly handled before, the first check could thus take up to the number of seconds defined in PUI_CHECK_UPDATES_INTERVAL.
