Ok, praps I've been a little too reticent

Xp Home SP2, no particular changes that I can think of, usual ms updates as they turn up (I relaise that could be a can of worms) but of interest with the attached fix, all the dll's were found with the exception of Oleaut32.
Possible cause?? I also use firefox but switched IE to default for the purposes of a fix & no good.

Quick thought, since OE is part of the OS, could I remove it as a component & then reinstate it as a bit of brute force, via the add/remove components in add/remove programs? I ask because I'm posting from home on vista & it ain't the same!
AVG free - never a prob before.
Windows firewall & belkin router - same
Yes, the cursor changes, just nothing on clicking.
Yep, copy & paste for links works just fine. In fact, no other problems of any nature within the system. Just this.
