Hi
Sorry for not replying sooner but I've been offline for a while. 1.38.485 worked fine deleting about 170mb in about 30 secs.
I just upgraded to 1.40.520, and although possibly faster than than 1.39.520, it still took 77 secs to clear 50meg. As I usually leave it until about 150meg plus, I'm not sure how useable it will be. I'll post again in a couple of weeks or so. Sorry I didn't retry with 1.39.520, but I've got pretty stingy download limits, and I didn't keep the old install file.
No new software added recently, not even XP updates from what I can recall. AVG updates daily, but no new versions recently that i can recall. Also updates on Spybot, but again no new versions recently.
