My apologies for the wait, but the staff are busy.
The problem lies with the IE Addons that are used with the browser. One of them is corrupted.
Open IE and on the Tool bar select Tools
> Internet Options
> Program Tab
and select the "Manage addon
In the next window there is a drop down box, choose the addons that are currently being used in IE and when they come up start with the bottom one and highlight it and choose to disable it.
Try to see if that fixes the problem. If it continues then disable the next one as well. Keep doing this until you find the bad one.
Not to worry. If a disabled addon is required then the yellow security bar will pop up notifying you of an active X problem with that site. Choose to allow the new Active X add-on to be downloaded and installed. Eventually you will find the bad one and it will be replaced with a good version.
You can then go back and remove the disabled ones.
And that should do the trick.
