Comment 8 for bug 454941

Previously, when closing the main window and re opening it, it would still show outdated information. It may be that it was running in the 'background' and shown in the panel and not shut down. I no longer recall.

Right now, i do not have it start upon login. Starting it manually, it shows 'updated 3 days ago' which is probably the last time i used update-manager. The last update via aptitude was an hour or few ago, so i guess tracking updates by other programs is unimplemented.

Here is a conjecture: i had aptitude running and then update-manager attempted update but could not due to resources being locked. After closing Aptitude, update-manager had some invalid state information which prevented it from operating properly.
