The system, which has a gig of RAM, has taken to running slowly by 'hanging' for a few minutes. It then operates okay for a few more minutes, before a cursor freeze again. Similar for Alt-Tab to swap between apps, just doesn't happen.

I've run Ad-aware, CCleaner and Spybot, plus a full AVG scan.

Tks,
