Dropped a grenade in XP, it seems. Now, I've had this before, but I can't recall how to get out of it. It's to do with typing: I can type in native Windows apps (Word, notepad) as normal, but Agent will only recognise alphanumerics (no return, backspace, delete etc) and I can't enter text into, for example, the google search box and it certainly won't let me enter a url into Firefox. I can get text into IE's address bar, but no spacebar or other functions. Also, Windows Desktop Search keeps opening, unbidden. I've removed Agent pro tem (as the first program that showed a fault) and I've performed two System Restores, back a day and a week respectively. AVG checks the whole machine every day and reports nothing and I'm up-to-date with Spybot and Ad-Aware checks: again, nothing to report. If anybody can understand my problem (well, this one, at least) and offer a solution, it'll be virtual beers all round. FFS, save me the agony of rebuilding my five-year-old XP Pro installation.
