I have now attempted the recommendations from your first response. There
were a couple of trojans and quite a bit of adware that McAfee had missed.
One thing I am wondering is whether McAfee actually searches comprehensively,
or only in the files for the user that is logged in. I had to re-run one of
the adware progs you suggested as each user to catch everything, even though
I am the administrator.
Problems with the control panel and drop down menus appear to have cleared
up, but not sure if this is as a result of what I have done, or 'just one of
those things'.
Problem with locking up still occurs. In answer to your second response,
this occurs randomly and I have not been able to associate it with any
particular action on my part, so I can't re-create it.
It is a recent thing, so maybe McAfee is responsible - I have had problems
with it before! Have two machines and other one is fine, though.
Your comments re IE Explorer are interesting. That does do some odd things,
for example on both my machines I get a script error message every time
Messenger opens up. I wouldn't recognise an 'odd' task from a normal one, as
I don't know what most of them are doing anyway!
As for the Start button thing , I think you misunderstood me. That related
to the now apparently solved control panel thing when I accessed control
panel via the start button. Explorer didn''t crash until I opened or did
something with the control panel. Accessing control panel another way, e.g.
by double clicking 'my computer' worked fine.
Will try sfc/scannow (from Run, I assume) and see if that has any effect.
Another issue which may be related to the problem; When I log on,
everything proceeds fine up to a point and then the system hangs, giving me
a wait timer if I move the cursor into the lower task bar area. After a
while, this clears up, the desktop refreshes itself and things are back to
nornal. Maybe that is simply an example of the locking up which I can
reproduce!
