Very impressed with v1.45, all working fine except for this possible bug (Vista x64 SP2): When you hover over the Malwarebytes icon in the System Tray, I see the database version, but this version number does not seem to get updated once the database has updated via the realtime update option. For example, Vista booted up this morning, hovering over the icon shows database version 3935 (30/03/2010). After a few minutes the realtime update kicks in and I see a popup balloon stating that the database has updated to 3936. But hovering over the icon still displays version 3935 (30/03/2010). Checking the Update tab in the main Malwarebytes screen shows that the database is version 3936. XP seems to be OK.
