What if you right click the IE icon on the desktop and choose Start
Without Add-ons?
Or go to Start | All Programs | Accessories | System Tools | Internet
Explorer (No Add-ons).
Many thanks for your replies Bill & Frank.
I re-booted the PC before I started trying this, I still get the same
error though when trying to save a page (in any format and several sites
just in case a particular site is an issue).
I can, though, now choose 'Printer Friendly Version' without any errors.
(During the course of doing this I discovered I'd forgotten to plug my
printer in, that Vista can't discover a printer on a Draytek Vigor, that
my Terastation has a printer port I'd forgotten about, that my printer
lead is too short to reach the printer port and it hurts when you bash
your head on the desk while crawling around connecting cables up).
Having set the printer up I can't chose 'Print To File' - it's grayed out
permanently.
I then thought I'd try e-mailing the page again.
(During the course of doing this I discovered that Vista won't play with
'TheBat!', that setting up Windows Mail is pretty easy and, after half an
hour, the mail server I was trying to use was down).
I have now managed to email it to myself from Windows Mail and can save it
from there so that part works.
However, I can still not save pages in any format from IE - even using it
with add ons disabled, although I do now know how to set up a network
printer in Vista and how to set up Windows Mail (and that it looks worth a
try)
I don't have any add ons in IE. I would like to try and fix this if
possible - I like to save files in mht format - and would appreciate any
more suggestions. If it comes to it I don't mind doing a clean install and
starting from scratch, my data is not on the 'C' drive and there are only
a few apps installed at this stage.
