I don't really understand what I'm doing here but I uninstalled only the HP Share to web stuff by right clicking on the "share to web" desktop icon and then clicking on the unistall programme link. This seems to have fixed all problems.
Sounds about right. From what I've read the problem is compatability between this MS Patch and HP Share to web.
By uninstalling HP Share to web you have probably resolved the conflict.
If you do need HP Share to web back on your machine, try to find an updated version on the HP Website. If you don't need it, then I should quit whilst you are ahead
