Hi Pkshadow. Thanks for your quick reply :-) I tried your suggestion and all I got was a blank page with the little circle in the browser tab just going round and round for 5 minutes before I closed it. I am running IE 11 under Win 7 (64 bit). I would appreciate any further suggestions.

update: One reason I switched to Firefox from IE was because IE 11 couldn't open my previously saved .mht web pages. So when I tried your suggestion of using IE11 to view my .mht files, I encountered the same problem. Doing some research on this IE11 problem I was having led me to uninstall and then re-install an earlier version and it is now opening my .mht files.

Over the years, I have taken a liking to Firefox and if possible, may try to revert to an earlier version so that I could continue to use it as I had been.

Thanks for your help and pointing me in the right direction.

It does work as I changed a html file to that then when double clicked it opened in IE. Also the info came from Microsoft.

Try making a copy of the file and changing it to just html and see what happens.

Can download a Web Editor and open it in that http://bluegriffon.org/ and see about saving it in that or open and extract the info or work with it...really do not know.

Can try this so can get your files back and save them in another format that works on all browsers and is supported by others.
