Browser plugin, activex control, scanner bits. Online update. == Application online update checking == When we start LO, first InitUpdateCheckJobThread is created, via UpdateCheckJob::execute() (from extensions/source/update/check/updatecheckjob.cxx), as a reaction to a "onFirstVisibleTask" event. It waits 25 seconds (so that it does not interfere with the startup itself), and then calls UpdateCheck::initialize() (from extensions/source/update/check/updatecheck.cxx). This creates one more thread, UpdateCheckThread, that regularly checks whether we have reached the time when we should ask for the update. If yes, asks for that, and shows the download button in the menu (if the new update is available).
