Hi,
thanks for the prompt answer.
I did perform a full scan using Norton-Antivirus but
nothing was detected.
I think I know what provoqued this problem but I'm not
sure. Here is what happened :
My portable computer is an HP omnibook xt6200. I opened
the Mouse properties from the control panel and from
the 'More features' (synaptics) tab, activated the Slow
Motion Key and Constrained Pointer Key'. Coincidence but
as from then, the problem occurred but I did not realise
it at the time. I deactivated these options but it did not
solve anything.
I thought that may be one of the OLE2 files were damaged
and I installed the Office SP2 from the Office Updates
which solved the problem.
I reactivated the above features and the problem is back
again.
I did a repair installation from the Office Setup. Did not
solve.
I did a full uninstall of the MS Office but it seems that
some of the SP2 OLE files were not removed/restored. I
reinstalled Ms Office XP Professional with Front Page. Did
not solve.
I reinstalled the Ms Office SP2 (the setup did not ask to
reboot this time, so most probably did not replace any new
files). Still did not solve the problem.
Now may be its a virus or a damaged OLE system file.
The solution would be to force a replace of the office
system files from a service pack or setup, but how is this
done ?
