Strangely, HL2 is not pausing here anymore (nor EP1 or EP2 for that matter). Did you receive the latest update for HL2?
Yes, all updates released so far had been automatically downloaded by steam client. Most strangely, now the bug shows itself when I start a new game, but no more happens when loading a save. Looks like there was something changed in HL2 engine during latest updates that partially fixed the bug.
